Color liquid crystal display device wherein the color polarizer having wavelength dependence of the polarizing efficiency

摘要

A color liquid crystal display device capable of displaying uniformly four colors of white, red, blue and green with high purity by multiplex driving is provided. In a system for effecting a multi-color display using a same display unit and utilizing retardation, at least one color polarizer is used between a pair of polarizers, which indicates a specified range wherein the polarizing efficiency of red or blue is relatively lower than that of green.
