Abstract
A projection color liquid crystal display apparatus includes a light source, and a light separator to which light emitted from the light source is inputted. The light separator separates the light inputted thereto into color lights of the three primary colors of red, green and blue, converts each of the color lights into one of p-polarized light and s-polarized light and outputs the polarized lights. In a light path of the light outputted from the light separator, a liquid crystal display element having a plurality of pixels arranged corresponding to the individual color lights obtained by the color separation of the light separator and a projection lens for projecting the light outputted from the liquid crystal display element to a screen are disposed.
