Transreflective liquid crystal display

Abstract

A transreflective LCD includes a plurality of pixels arranged in a matrix, each including a switching element, a backlight for supplying light to the pixels, and first, second, third, and fourth capacitors which are individually connected to output terminals of the switching elements. Each pixel includes a transmissive area for transmitting light from the backlight, and a first reflective area and a second reflective area for reflecting light originating from the exterior environment. In this way, the reflective area is divided into two areas and the auxiliary capacitor is provided in one area of the two. The gamma curves of the transmissive mode and the reflective mode can meet together at a curve by controlling the dimension ratio and the voltage ratio of the two areas. In this way, color display showing uniform color sense can be realized without regard to changes in mode.
