Abstract
A liquid crystal display device has a pair of transparent substrates facing each other with a liquid crystal layer therebetween. First and second phase difference plates and a first polarizing plate are formed sequentially on one of the transparent substrates, while a reflector, a third phase difference plate, and a second polarizing plate are formed sequentially on the other of the transparent substrates. The reflector is a metal reflection film on a base material with concave portions formed thereon. The metal reflection film includes a plurality of concave surfaces corresponding to the concave portions that face the transparent substrate. The thickness of the metal reflection film is within the range of 5 to 50 nm.
