摘要:
A liquid crystal display device in which light from a light source enters a liquid crystal panel and exits therefrom for projection of an image and includes a heat conducting member and a cooling unit. The heat conducting member is contacted with at least one of a light incident surface and a light outgoing surface of the liquid crystal panel, is light-transmissive, and has a larger area than a light transmitting area of the liquid crystal panel. The cooling jacket, which comprises a flow channel for a cooling medium in its inside, is provided around the heat conducting member so that the flow channel exists only outside of the light transmitting area in a surface direction of the liquid crystal panel.

The present invention provides a liquid crystal display device and a liquid crystal cooling unit, which are reduced in noise and have high cooling capability, and in which air is not directly blown on a liquid crystal panel module or a polarizing plate. A cooling jacket having an internal flow channel is formed by being adhered to a periphery of a light-transmissive, highly heat-conducting sapphire plate larger than a light transmitting area to which a polarizing film is applied or attached, by means of a highly heat-conducting adhesive. A liquid crystal cooling unit is formed by clamping the liquid crystal panel module by inserting a light-transmissive, highly heat-conducting substance. Further, the liquid crystal panel module and the polarizing film are cooled by circulating a cooling medium in the internal flow channel of the cooling jacket.
