Abstract

A color filter substrate and a liquid crystal display using the color filter substrate, wherein the color filter substrate includes a plurality of green photoresists. G(λ) is the transmission spectrum of the green photoresist, CMF_x(λ) is the color matching function formulated by the International Commission on Illumination, where the maximum value of G(λ)×CMF_x(λ) between the wavelengths of 450 nm and 510 nm is M1, the maximum value of G(λ)×CMF_x(λ) between wavelengths of 550 nm and 590 nm is M2, and the ratio of M1 to M2 is less than or equal to 0.04, and the half-maximum width of the peak of G(λ) is D , and D is less than or equal to 90 nm. The invention can improve the color saturation of the liquid crystal display.

Description

technical field [0001] The present invention relates to a display device; in particular, to a liquid crystal display and its color filter substrate. Background technique [0002] With the advancement of flat-panel display technology and the advantages of light weight, small size and power saving of flat-panel displays, flat-panel displays have become more and more popular. Common flat panel displays include Liquid Crystal Display (LCD), Plasma Display Panel (PDP), Organic Light Emitting Diode Display (OLED Display), and Electrophoretic Display (EPD), etc. Among them, the liquid crystal display has the highest penetration rate. [0003] The liquid crystal display includes a liquid crystal display panel (LCD panel) and a backlight module (Backlight Module), wherein the backlight module can provide flat light to the liquid crystal display panel. In addition, the color filter substrate of the liquid crystal display panel is an important element for colorizing flat light. [0...
