Abstract:
1. A liquid crystal display device, comprising: a liquid crystal panel mounted on a light incident plane of a prism; a first sapphire substrate disposed between the liquid crystal panel and the light incident plane of the prism, the first sapphire substrate directly contacting the liquid crystal panel; a polarizing plate disposed between the first sapphire substrate and the light incident plane of the prism, the polarizing plate directly contacting the first sapphire substrate; a phase difference plate and a second sapphire substrate disposed between the polarizing plate and the light incident plane of the prism, one of the phase difference plate and the second sapphire substrate directly contacting the polarizing plate, the other of the phase difference plate and the second sapphire substrate directly contacting the light incident plane of the prism; and a cooling device forcedly cooling the integrated structure statically, the cooling device including at least one of a Peltier cooling component and a heat pipe as a heat sink of the cooling device and directly contacting the prism, wherein the liquid crystal panel, the light incident plane of the prism, the phase difference plate, the first sapphire substrate, the second sapphire substrate, and the polarizing plate are an integrated structure that effects cooling of its components.
