摘要： A projector includes: a liquid crystal panel in which liquid crystal molecules to be irradiated with light from a light source are sealed; a polarizing plate disposed in a position to face the liquid crystal panel; and an optical compensation sheet disposed between the polarizing plate and the liquid crystal panel and compensating birefringence of the liquid crystal molecules. The optical compensation sheet can be adjusted by being swung in a plane orthogonal to the optical axis, and its normal can be adjusted so as to be tilted from the optical axis.

摘要： An openable lid is provided to cover an opening formed in the upper end of a casing of a projection type image display apparatus. Formed on the base of the casing and underneath the opening is a first mount section, on which a plinth is mounted with fixing screws. A prism assembly incorporating at least three liquid crystal panels and three polarization plates for RGB colors integrally attached to a color compounding prism is securely fixed on the plinth. The first mount section is provided with engagement members fixed thereon for temporarily holding the plinth that bears thereon the prism assembly to thereby prevent the plinth from falling downward if the screws are removed to dismount the plinth from the first mount section even when the image display apparatus is installed upside down on a ceiling for example and the lid is open. This permits easy replacement of parts of the projection type image display apparatus that is installed upside down, and thus greatly improves maintenance efficiency of the projector.
摘要翻译：提供可打开的盖以覆盖形成在投影型图像显示装置的壳体的上端中的开口。在壳体的底部和开口下方形成有第一安装部分，底座上安装有固定螺钉。将至少三个液晶面板和三个用于与彩色复合棱镜一体连接的RGB色彩的偏振板组合在一起的棱镜组件牢固地固定在底座上。第一安装部分设置有固定在其上的接合构件，用于临时保持承载在其上的基座上的棱镜组件，从而防止如果从第一安装部分移除螺钉以将底座从第一安装部分卸下，则即使图像显示装置倒置在天花板上，盖子打开。这样可以容易地更换颠倒安装的投影型图像显示装置的部件，从而大大提高了投影机的维护效率。
