Abstract
A projection type liquid crystal display according to the present invention comprises a dichroic prism for separating or synchronizing a light to provide fundamental colors for color display, and a unit for enlarging and projecting a transmitted light from the liquid panel. The liquid panel has one surface fixedly attached to a transparent member and the other surface integral with the dichroic prism directly or through at least one optical component. In the projection type liquid crystal display, the light which provides fundamental colors for color display and is separated or synchronized at the dichroic prism is incident on the light incidence surface of the liquid panel through the transparent member or the dichroic prism without contacting with the air in the space. The light incident on the liquid crystal panel is irradiated from the light outgoing surface of the liquid crystal panel through the transparent member or the dichroic prism without contacting with the air in the space and thereafter enlarged and projected. With this arrangement, it is possible to simplify the structure of the peripheral optical systems of the liquid crystal panel and to improve image quality.
