Abstract:
1. An image display apparatus, comprising: a light source apparatus including a light source substrate on which a plurality of light sources is arranged, a secondary light source member on which a secondary light source surface is formed when the secondary light source member receives light from the plurality of light sources, and a frame with one end attached to the periphery of the light source substrate and the opposite end attached to the periphery of the secondary light source member so that the light source substrate and the secondary light source member are situated a predetermined distance opposite to each other, wherein the frame has at least one pair of opposing reflective surfaces, and each individual surface comprising the pair of opposing reflective surfaces is inclined in the same direction and at a predetermined angle relative to the normal to the light source substrate; an image display element that optically modulates a light beam from the light source apparatus and emits said light beam; and an optical system having a decentered reflective curved surface, the optical system guiding the light beam modulated by the image display element to an observer.
