Abstract
A liquid crystal display for a projector, including a pair of substrates, a liquid crystal sealed in a space defined between the pair of substrates, and a translucent radiating plate mounted on at least one of the pair of substrates through a translucent adhesive. With this configuration, heat generated in the liquid crystal display can be efficiently dissipated to the outside with a simple structure. Further, degradation of a displayed image quality due to variations in cell gap can be prevented.

The liquid crystal display comprising:
- a drive substrate having a display region in which a matrix of pixels is arranged and a drive circuit region;
- an opposing substrate opposed to said drive substrate;
- a liquid crystal layer held between said drive substrate and said opposing substrate;
- a first translucent radiating plate mounted on a surface of said drive substrate opposite to said liquid crystal layer through a translucent adhesive;
- a black metal sheet having high thermal conductivity formed on a surface of said opposing substrate opposite to said liquid crystal layer at a portion thereof corresponding to said drive circuit region;
- a second translucent radiating plate mounted on said opposing substrate through said black metal sheet;
- and
- an air gap formed so as to be surrounded by said opposing substrate, said black metal sheet, and said second translucent radiating plate.
