Abstract:
A display unit comprising image displaying means having pixels arranged two-dimensionally, plate-shaped illumination means having fine light-emitting points arranged two-dimensionally corresponding to the pixels and being placed on the backside of the image displaying means, and fine optical elements for introducing light emitted from the fine light-emitting points, which are arranged two-dimensionally corresponding to the pixels, to the respective pixels,wherein the pixels, the fine optical elements and the fine light-emitting points are arranged so that optical axes connecting the respective fine light-emitting points and the respective fine optical elements corresponding thereto pass through respective pixels corresponding to the fine optical elements and the fine light-emitting points, and the optical axes intersect substantially at a prescribed point within a distance of a near point of vision of an eye from a display face of the image display means, and the fine optical elements form a virtual image of the fine light-emitting points corresponding thereto at a distance longer than a distinct vision distance of the eye from the prescribed point.
