Abstract
A single gap transflective liquid crystal display (LCD) using an in-plane switching (IPS) mode is being studied. In the IPS mode, the degree of the rotation of the LC director, between and above electrodes is different. When it is 45° between the electrodes, it is only 22.5° above the electrodes for an optimized cell design. Utilizing this mechanism and an in-cell retarder with a quarter-wave plate that is used below the LC layer, the transflective IPS mode is realized as such that the area between the electrodes is used as a transmissive part and the area above the electrodes is used as a reflective part.
