Abstract
The present invention provides a liquid crystal display device, which includes a liquid crystal panel as one of optical components for transmitting, absorbing or reflecting light. At least any one of the optical components is comprised of a sapphire substrate. The optical components further include a lens, and a polarizer having a polarizer film and a retaining plate for retaining the polarizer film, and the liquid crystal panel may include a transparent substrate. In this case, any one of the lens, the retaining plate and transparent substrates is comprised of a sapphire substrate, and thus, it is possible to provide a transmission type liquid crystal display device which transmits light from the light source through the lens, the polarizer and the liquid crystal panel so that light is projected.
