Abstract
A wide-view single cell gap transflective liquid-crystal display (TR-LCD) using the fringe field switching effect is proposed by incorporating a quarter-wave in-cell-retarder below the liquid-crystal (LC) cell in the reflective part. By optimizing the angle between the electrode stripes and the LC rubbing direction in the transmissive and the reflective regions, this TR-LCD exhibits a high optical efficiency and good match between the voltage-dependent transmittance and reflectance curves. Without using any phase compensation films, this TR-LCD exhibits a wide view with 10:1 contrast ratio over a 60° viewing cone in the transmissive mode and over a 40° cone in the reflective mode, which is adequate for mobile displays.
