Abstract

The invention discloses a color photoresist containing fluorescent dye. The color photoresist can be used in a color filter to form a color photoresist layer, wherein the fluorescent dye is dissolved in a solvent of the photoresist, and the fluorescent dye has a certain color and also can absorb ultraviolet light or emit light according to the wavelength of the color to be displayed so as to increase the brightness, and significantly improve the brightness and chromaticity of the color photoresist. The invention also discloses a transflective liquid crystal display device, wherein the color filter of the device contains the color photoresist.

Description

technical field [0001] The invention belongs to the field of liquid crystal display, and in particular relates to a color photoresist and a transflective liquid crystal display device containing the color photoresist. Background technique [0002] The color filter is a key component for liquid crystal display devices to achieve colorization, and it is also a key component with high cost in liquid crystal display devices. The quality and cost of color filters play a vital role in the color display performance of LCDs. A color filter is generally composed of a glass substrate, a black matrix, a color photoresist layer, a protective layer, an ITO electrode layer, and the like. [0003] At present, the preparation method of color filter mainly adopts the pigment dispersion method. The pigment dispersion method is to disperse the pigment in an organic solvent, prepare a color photoresist and coat it on a glass substrate, and the polymerization of the photosensitive resin in the...
