Abstract
A liquid crystal display device () includes an upper substrate (), a lower substrate (), and a liquid crystal layer () between the upper substrate and the lower substrate. The upper substrate includes an upper polarizer () and a color filter layer (), the upper polarizer being an extraordinary type polarizer. The lower substrate includes a reflective film (). A multiplicity of pixel electrodes () and common electrodes () are positioned at the lower substrate, for applying a voltage to the liquid crystal layer. The display device has a wide viewing angle, can work at high temperatures, and is relatively thin and compact. Further, the color filter layer is positioned above the upper polarizer. Optical beams reach the color filter layer after passing back through the liquid crystal layer and the upper polarizer. This reduces or eliminates color filter de-polarizing, and yields a high contrast ratio over wide viewing angles.
