Abstract
A transflective liquid crystal display providing a bright displayed image of high contrast in the transmission mode with less dependence on the viewing angle by combining a polarizer with an optically anisotropic element having a liquid crystal film in which a twisted nematic alignment stricture is secured to produce a circular polarizer and disposing the circular polarizer on the rear side of a transflector in the transflective liquid crystal display.
