An image display apparatus includes a display having an image display surface which displays a two-dimensional image of an object including a three-dimensional object, and an image transmitting panel spaced apart from the image display surface for creating an imaging plane displaying a real image of the two-dimensional image in a space opposite to the display. The image transmitting panel and the imaging plane are non-parallel with each other.

What is claimed is: 1. An image display apparatus providing an enhanced impression of an optical perspective, said apparatus comprising: at least one micro lens array assembly, each comprising at least one micro convex lens board having two lens array halves mounted substantially parallel to each other, each said lens array half comprising a transparent flat plate with a plurality of convex lenses arranged in a matrix on each flat surface thereof and said lens array halves being aligned appropriately in said micro lens array to thereby form a lens system for each said micro convex lens in each said matrix of convex lenses; and for each said at least one micro lens array assembly, a display located relative to said micro lens array assembly to project a two-dimensional image through said micro lens array assembly to be focused in a space on an opposite side thereof as an imaging plane, each said at least one micro lens array assembly displaying an erect real image of the two-dimensional image, wherein a shape of said imaging plane relative to a viewer provides an enhanced three-dimensional impression of said two-dimensional image by providing an illusion of depth in the displayed real image that is consistent with a three-dimensional object. 2. The apparatus of claim 1, wherein a magnification of said erect image is approximately unity. 3. The apparatus of claim 1, wherein said shape of said imaging plane providing said enhanced three-dimensional impression is caused by at least one of: locating said least one micro lens array assembly relative to said display in an inclined orientation consistent with a perspective effect if a viewer were viewing said three-dimensional object; and providing a gradual change of curvature of said convex lenses on at least one said flat surface of at least one of said two lens array halves, thereby causing said imaging plane to bend in space consistent with said perspective effect of said three-dimensional object. 4. The apparatus of claim 3, wherein said at least one micro lens array assembly comprises a plurality of micro lens array assemblies that together provide for a composite image presentation, each said micro lens array assembly having a corresponding display, wherein each said micro lens array assembly and its corresponding display separately contributes to an enhanced three-dimensional impression for an overall image, thereby providing said composite image wherein there are different components of which each contributes to said enhanced three-dimensional impression. 5. The apparatus of claim 1, wherein said imaging plane is flat. 6. The apparatus of claim 1, wherein said imaging plane is curved. 7. A method of providing an enhanced three-dimensional impression of a two-dimensional image, said method comprising: providing a micro lens array assembly comprising a plurality of convex micro lenses arranged in at least one matrix, said micro lens array assembly comprising at least one micro convex lens board having two lens array halves mounted substantially parallel to each other, each said lens array half comprising a transparent flat plate with a plurality of convex lenses arranged in a matrix on each flat surface thereof and appropriately aligned to thereby form a lens system; and projecting a two-dimensional image through said micro lens array assembly to be focused on an opposite side as an imaging plane, said imaging plane being a set of points in a space where said two-dimensional image is focused by said plurality of micro lenses in said at least one matrix, wherein said enhanced third-dimensional impression results from a shape of said imaging plane in space consistent with a perspective view of a three-dimensional object and said shape is caused by at least one of: locating said at least one micro lens array assembly relative to said display in an inclined orientation that is consistent with said three-dimensional perspective; and providing a gradual change of curvature of said convex lenses so that said imaging plane shape is consistent with said three-dimensional perspective in at least one said matrix of convex micro lenses, and wherein said micro lens array assembly displays an erect real image of the two-dimensional image at a same magnification. 8. An image display apparatus, comprising: a display for displaying a two-dimensional image; and a micro lens array spaced apart from the display for creating an imaging plane in a space opposite the display, the micro lens array being an upright image optical system, said micro lens array assembly comprising at least one micro convex lens board having two lens array halves mounted substantially parallel to each other, each said lens array half comprising a transparent flat plate with a plurality of convex lenses arranged in a matrix on each flat surface thereof and said lens array halves are aligned appropriately in said micro lens array to thereby form a lens system for each said micro convex lens in each said matrix. 9. The image display apparatus according to claim 8, wherein a plurality of said displays and said micro lens arrays together provides a composite image. 10. The image display apparatus according to claim 8, wherein the micro lens array has a magnification of approximately unity. 11. The image display apparatus according to claim 8, wherein the micro lens array is flat and the display partly bends relative to the micro lens array. 12. The image display apparatus according to claim 8, wherein the display is positioned within a focal depth of said micro lens array. 13. An image display apparatus comprising: a display for displaying a two-dimensional image; and a plurality of micro lens arrays spaced apart from the display such that each said micro lens array extends at a non-right angle with respect to the display and creates an erect real image of part of the two-dimensional image at a same magnification in a space opposite the display, each said micro lens array comprising at least one micro convex lens board having two lens array halves mounted substantially parallel to each other, each said lens array half comprising a transparent flat plate with a plurality of convex lenses arranged in a matrix on each flat surface thereof and said lens array halves are aligned appropriately in said micro lens array to thereby form a lens system for each said micro convex lens in each said matrix. 14. The image display apparatus according to claim 13, wherein said display has a plurality of sections which correspond to the plurality of micro lens arrays, respectively, and each of the plurality of sections displays different images or substantially different portions of a composite image. 15. The image display apparatus according to claim 13, wherein the display is positioned within a focal depth of each said micro lens array. 16. The image display apparatus according to claim 15, wherein distances between said plurality of sections of the display and the corresponding plurality of micro lens arrays are equal to each other. 17. The image display apparatus according to claim 13, wherein an imaging plane resulting from said plurality of micro lens arrays has a flat shape and inclines toward said micro lens array. 18.
