Active matrix polymer dispersed liquid crystal display device with flourescent film

摘要

A liquid crystal device includes a TFT or active element substrate on which TFTs and pixel electrodes are arranged in the form of a matrix, a counter substrate having a counter electrode formed thereon and arranged to oppose the active element substrate, a polymer dispersed liquid crystal layer arranged between the active element substrate and the counter substrate and having a polymer resin and a liquid crystal which are dispersed, and a fluorescent film arranged on the pixel electrode. The device displays an image by controlling scattering, absorption, and transmission of light passing through the polymer dispersed liquid crystal layer. The phosphor film converts part of supplied light into fluorescent light having a predetermined wavelength and outputs colored light. Light used for a display is increased in intensity by the fluorescent light emitted from the phosphor film, thereby displaying a bright image.
