| Abstract(in English) | A bright reflective LCD without a backlight is a key device for portable information systems. The guest-host LCDs use absorption effect of dichroic dyes and have a wide viewing angle cone. So that, complicated designs of optical compensation in birefringence or optical rotatory power modes have no use of the GH-LCDs. Black and white color of the GH-LCDs works as a light shutter of a full color display with micro-color filters and the display must match achromatic color precisely. Then it is necessary to mix dyes for achromatic display in the GH-LCDs. In this work, the design was carried out with the Newton-Raphson method in order to obtain the optimum dye concentration. As a result, the relationship between the dye concentration and the half width of spectra of dyes was clarified. The process gives us a helpful guideline in fabrication of the reflective color LCD and it is expected that the precise color matching improves the quality of LCDs. |
