Patent ID: 7139051

Claim:
A reflective liquid crystal display (LCD) of high aperture ration, high transmittance and wide viewing angle comprising: a lower substrate; an upper substrate opposed to the lower substrate and being separated therefrom by a selected first distance; a liquid crystal layer sandwiched between the lower and upper substrates comprising a plurality of liquid crystal molecules; a gate bus line and a data bus line formed on the lower substrate to define a pixel; a counter electrode having a first width and a pixel electrode having a second width formed at an inner surface of the lower substrate, wherein the counter and pixel electrodes are horizontally separated by a selected second distance to generate fringe field between the counter and pixel electrodes, wherein the second distance is less than either the first width or the second width; wherein the most of the liquid crystal molecules in upper portions of those electrodes are sufficiently driven in both the horizontal and vertical directions by the fringe field between said counter and pixel electrodes; a thin film transistor provided adjacent to an intersection of the gate bus line and the data bus line and transmitting a signal of the data bus line into the pixel electrode when the gate bus line is selected; a polarizing plate disposed at an outer surface of the upper substrate; a reflecting plate disposed at an outer surface of the lower substrate; and a quarter wave plate sandwiched between the reflecting plate and the lower substrate, wherein both counter and pixel electrodes are made of a transparent conductor, and wherein the selected first distance between the upper and lower substrates is greater in length than the selected second distance between the counter and pixel electrodes.
