摘要:
An image display apparatus includes: a plurality of light sources for emitting light; an optical uniformizing portion for uniformizing light emitted from the plurality of light sources; a total reflection portion disposed above the plurality of light sources, the total reflection portion totally reflecting light from the optical uniformizing portion; an optical guide portion for guiding light totally reflected at the total reflection portion; an optical diffusion unit for diffusing light from the total reflection portion and outputting the diffused light; an optical parallelizing unit for parallelizing light from the optical diffusion unit; and a liquid crystal panel for modulating light from the optical parallelizing unit into an optical image in accordance with an image signal and displaying the optical image.
