    • 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.
    • 显示单元包括:光调制单元,其包括有效区域,并且调制进入有效区域的照明光; 发光单元,其包括能够发光或停止发光的多个发光区域,并且与设置在有效区域中的多个有效图像调制区域的轮廓形状基本相似; 以及作为照明光将作为发光单元的发光的结果的光束引导到光调制单元的有效区域中的有效图像调制区域上的临时照明系统。
