ABSTRACT:
A display unit includes: a light modulation unit that includes an effective area, and modulates an illumination light entering to the effective area; a light-emitting unit that includes a plurality of light-emitting areas that can be made to emit a light or stop emitting a light, and are substantially similar in outline shape to a plurality of effective image modulation areas set in the effective area; and a critical illumination system that guides, as the illumination light, a luminous flux as a result of light emission of the light-emitting unit onto the effective image modulation areas in the effective area of the light modulation unit.
