Abstract
A reflective multicolor matrix LCD with micro color filters is investigated. In order to improve the brightness of the LCD, contrast and brightness of various liquid-crystal display modes are analyzed. This analysis suggests the choice of the phase-change-type guest-host mode. The optimal parameters for this mode are derived. In addition, the transmission spectrum of the micro color filters is investigated and the optimal doping concentration of the dye in the color filters is determined. This results in a reflective color LCD with acceptable brightness.
