Abstract
A projection liquid crystal display device including a first optical system that splits a light beam outputted from a light source into a red light beam, a green light beam, and a blue light beam, a red liquid crystal panel, a green liquid crystal panel, and a blue liquid crystal panel that modulate the red light beam, the green light beam, and the blue light beam, respectively, a second optical system that combines the modulated red light beam, the modulated green light beam, and the modulated blue light beam into one optical path, and a projection lens system that projects a light beam outputted from the second optical system on a projection surface, in which a configuration of a liquid crystal layer of the red liquid crystal panel is different from respective configurations of liquid crystal layers of the green liquid crystal panel and the blue liquid crystal panel.
