ABSTRACT:
A color liquid crystal display device is composed of first and second liquid crystal display cells aligned over each other, in which each cell includes a pair of color polarizers having respective polarization axes which are oriented at right angles to each other. The color polarizers of each cell contain at least one color which is the complement of the color contained in the other color polarizer. In this way, display contrast and brightness can be enhanced by allowing a higher ratio of picture elements to be utilized for monochromatic displays.
