ABSTRACT:
A transflective color liquid crystal display (200) with internal rear polarizer (275) has a front polarizer (260), a front substrate (210), a first color filter layer (212), a front transparent electrode (240), a liquid crystal layer (250), a rear transparent electrode (230), a rear polarizer (275), a reflector (235), and a rear substrate (220). The inclusion of an internal rear polarizer (275) results in little optical path difference between a reflective mode and a transmissive mode of the transflective color LCD (200). The internal rear polarizer (275) also results in little parallax, because the internal reflector (235) is very close to an image-forming layer (250). Additionally, a second color filter layer (214) can be added behind the internal reflector (235) to enhance the brightness and color saturation of the transflective color LCD (200) with internal rear polarizer (275) during the transmissive mode.
