Abstract
A liquid crystal display device comprising a first display of twisted-nematic (TN) or guesthost (GH) type in front of a second LCD of TN type in which a multicolor polarizer is provided on one cell substrate. The multicolor polarizer consists of two layers and multiple picture elements. The color polarizers of one layer of the multicolor polarizer have different wavelength regions and absorption axes perpendicular to the polarizer elements of the other layer.
