What is claimed is: 1. A stereoscopic image display apparatus, comprising: an image display unit which displays a combined image formed by combining a first, second and third viewpoint images corresponding to a first, second and third viewpoints different from one another in the horizontal direction, and includes a first pixel group displaying the first viewpoint image, a second pixel group displaying the second viewpoint image and a third pixel group displaying the third viewpoint image; a mask member which has a plurality of aperture portions guiding each light from the first, second and third pixel groups to the first, second and third viewpoints, respectively; a lenticular lens array which is arranged between the image display unit and the mask member and has a plurality of lenses with only refractive power in the vertical direction; and a switching control circuit that makes the image display unit display the plurality of combined images, in which arrangement of the first, second and third pixel groups are mutually different, and that switches arrangement of the aperture portions in the mask member with synchronizing with the switching of these combined images, wherein each pixel adjacent to each pixel of the first pixel group in the horizontal and vertical directions is not the pixel included in the first pixel group, each pixel adjacent to each pixel of the second pixel group in the horizontal and vertical directions is not the pixel included in the second pixel group, each pixel adjacent to each pixel of the third pixel group in the horizontal and vertical directions is not the pixel included in the third pixel group, the image display unit has a fourth, fifth and sixth image pixel groups different from the first, second and third pixel groups, the fourth, fifth and sixth image pixel groups corresponding to a fourth, fifth and sixth viewpoints different from the first, second and third viewpoints, the patterns of arrangement of the aperture portions are six, and the aperture portions of the mask member are formed by repeating the pattern of the arrangement of three aperture portions in a predetermined area in the horizontal and vertical directions. 2. The stereoscopic image display apparatus according to claim 1, wherein an optical member arranged between the image display unit and the mask member is only the lenticular lens array.
