ABSTRACT:
An LCD projector includes: a light source assembly for supplying light source required for the LCD projector; an image generating mechanism for generating image to be projected, having an LCD panel; a projection objective lens assembly for projecting the image generated by the image generating mechanism onto a screen; and a cooling mechanism for cooling off the surface of the LCD panel of which the temperature is raised due to the radiation of the light source. A thermal diffusion film having good transparency and thermal diffusivity is attachd to the surface of the LCD panel on the one side nearer to the light source assembly so as to facilitate homogeneous thermal diffusion in the surface of the LCD panel, and thus prevent deterioration of quality of projected image due to thermal shimmering caused by cooling air flow coming from the cooling mechanism.
