Abstract

A transflective color display having apertures in reflective electrodes through which light from a backlight (9) passes in the transmissive mode. The switching behavior for both the reflective and the transmissive mode is made identical by introducing a retardation plate (11). The transmission efficiency is further increased by using only a monochrome green mode in transmission.
