What is claimed is: 1. A liquid crystal display apparatus comprising: a liquid crystal panel for forming an image; at least one point-like light source for applying light to the liquid crystal panel; a light source substrate for mounting the point-like light source; a cabinet for holding the liquid crystal panel; and a plate-shaped member provided outside of the light source substrate; wherein the light source substrate is attached from the outside to a backside surface of the cabinet opposed to a surface opposite to a display surface of the liquid crystal panel and is detachable from the outside, and the light source substrate is attached to the cabinet through the plate-shaped member. 2. A liquid crystal display apparatus according to claim 1, wherein each of the plate-shaped member and the cabinet comprises a screw hole into which a screw is inserted, and wherein the light source substrate is attached to the cabinet by inserting the screw into the screw holes. 3. A liquid crystal display apparatus according to claim 2, wherein the plate-shaped member is made of material including metal. 4. A liquid crystal display apparatus according to claim 1, wherein a circuit pattern on the light source substrate is present in only a portion other than a contact portion with the plate-shaped member. 5. A liquid crystal display apparatus according to claim 1, wherein the light source substrate is attached to the plate-shaped member through electrical insulating material or material with good thermal conductivity. 6. A liquid crystal display apparatus according to claim 1, wherein the point-like light source is arranged in alignment along a direction that is substantially parallel with one side of the liquid crystal panel, and wherein a size of the light source substrate is set such that the light source substrate opposes at least one area of the liquid crystal panel. 7. A liquid crystal display apparatus according to claim 1, further comprising: an optical waveguide for guiding light emitted from the point-like light source to the liquid crystal panel, wherein the optical waveguide is provided between the liquid crystal panel and the cabinet. 8. A liquid crystal display apparatus according to claim 7, wherein the optical waveguide has a recess or a through hole and the point-like light source is received in the recess or the through hole. 9. A liquid crystal display apparatus according to claim 8, wherein the recess or the through hole is arranged in alignment along at least one side of the optical waveguide. 10. A liquid crystal display apparatus according to claim 7, wherein the light source substrate is made of material including metal. 11. A liquid crystal display apparatus according to claim 7, wherein a circuit pattern on the light source substrate is present in only a portion other than a contact portion with the cabinet. 12. A liquid crystal display apparatus according to claim 7, wherein the light source substrate is attached to the cabinet through electrical insulating material or material with good thermal conductivity. 13. A liquid crystal display apparatus according to claim 1, wherein the point-like light source is a LED. 14. An electronic equipment comprising the liquid crystal display apparatus according to claim 1. 15. An electronic equipment according to claim 14, further comprising: a mechanism temporarily opening an outer surface of a place corresponding to a position of at least the light source substrate in electronic equipment in which the liquid crystal display apparatus is incorporated into the inside.
