Abstract
A reflective color STN-LCD with a single polarizer and double retardation films has been investigated. The double retardation films arranged in front of LC-layer enabled the LCD to contain reflective electrodes inside the panel. This configuration achieved the bright image with no parallax. We have realized 7.8-in.-diagonal reflective color STN-LCDs(640 x 480) which have 15% reflectance, 1 : 14 contrast ratio, 4096 color capability and the sufficient color gamut.
