    • PROBLEM TO BE SOLVED: To provide a liquid crystal display unit capable of preventing external heat or force from being delivered to an optical compensation element and preventing unevenness of luminance from being generated on a projection screen.SOLUTION: A liquid crystal display unit 30B comprises: a liquid crystal panel 31 for modulating light; a light shielding plate 34 for controlling light L not to be incident on areas other than an effective pixel area R of the liquid crystal panel 31; an optical compensation element 35 arranged at sides on which the light L is incident in the liquid crystal panel 31 and the light shielding plate 34; and an optical compensation element holder 36 for holding the optical compensation element 35 to be separate from the light shielding plate 34 and not to be in contact with other members.
    • 要解决的问题:提供一种能够防止外部热量或力传递到光学补偿元件并防止在投影屏幕上产生亮度不均匀的液晶显示单元。 解决方案:液晶显示单元30B包括:用于调制光的液晶面板31; 用于控制不入射到液晶面板31的有效像素区域R以外的区域的光L的遮光板34; 配置在光L入射到液晶面板31和遮光板34的一侧的光学补偿元件35; 以及用于将光学补偿元件35保持为与遮光板34分离并且不与其它构件接触的光学补偿元件保持器36。 版权所有(C)2013,JPO&INPIT
