48.2: Advanced VA Mode with Fast Gray Scale Response and Wide Viewing Angle in a Bend Liquid Crystal Configuration

Abstract

Abstract We have developed “Transverse Bend Alignment (TBA) mode”, an advanced VA mode where liquid crystal materials are driven by a combination of a lateral field and a vertical field. We have made TFT‐LCDs with different spacings of comb‐shaped electrodes to reduce the steepness of the V‐T characteristics. By adjusting cell parameters, the LCD has wide viewing angle without color wash‐out in oblique directions and fast response between all gray scale levels.
