Abstract:
A liquid crystal display device comprising:a first liquid crystal cell made up of a liquid crystal layer sealed in a gap between a pair of transparent substrates having an electrode formed on each of the inner surfaces thereof, facing each other; a second liquid crystal cell disposed on a side of the first liquid crystal cell opposite from the visible side thereof and driven independently of the first liquid crystal cell; an absorption-type polarizing film disposed on the visible side of the first liquid crystal cell, for absorbing the light linearly polarized in the direction orthogonal to the transmission axis thereof, and a reflection-type polarizing film disposed on a side of the second liquid crystal cell, opposite from the visible side thereof for reflecting the light linearly polarized in the direction orthogonal to the transmission axis thereof, wherein said first and second liquid crystal cells control the strength of transmitted light by applying a voltage to a liquid crystal layer without changing a color tone of the transmitted light.
