Color film substrate and manufacturing method thereof, liquid crystal panel

Abstract

A color film substrate (100), comprising a substrate (110), a blue cut filter (120) provided on the substrate (110), and a plurality of color filter portions (130) provided on the blue cut filter (120). The plurality of color filter portions (130) comprises a plurality of blue filter portions (B), and the blue cut filter (120) corresponding to the blue filter portions (B) has different thicknesses. Also provided are a method for manufacturing the color film substrate (100) and a liquid crystal display panel (3000). The thickness of the blue cut filter (120) below each blue filter portion (B) is different, and the blue cut filter (120) corresponding to the blue filter portions (B) has different capabilities of weakening blue backlight, so that viewing angle color cast of the blue light filter portions is improved; moreover, there is no need to provide a black shield in each blue filter portion (B), thereby facilitating improving the aperture ratio of each blue filter portion (B).

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and in particular relates to a color filter substrate, a manufacturing method thereof, and a liquid crystal panel. Background technique [0002] The color of the liquid crystal display is realized by the color filter (CF, ColorFilter). However, traditional color filters have the disadvantages of poor utilization of light and low transmittance, and the transmission peak of traditional color-resist materials is wide, the color density is limited, and it is difficult to achieve a wide color gamut, which cannot satisfy users. Requirements for display quality. Quantum dots (Quantum Dots, QDs) are spherical semiconductor nanoparticles composed of II-V or III-V elements, and the particle size is generally between a few nanometers and tens of nanometers. Due to the small half-width of quantum dot materials and the luminescent color can be easily adjusted by the size, structure or composi...

AI Technical Summary

Problems solved by technology

Among them, the red filter part and the green filter part are filled with quantum dot materials, which allow users to receive red or green light at various angles, while the blue filter part needs to pass through the blue light source. Usually filled with transparent materials or even not filled, which will cause the problem of viewing angle deviation in the blue filter part

[0004] In order to improve the problem of angle deviation in the blue filter part, an existing method is to insert a black light-shielding body into the blue filter part, but this will cause the light transmittance of the blue filter part to decrease, which is not conducive to Increased aperture ratio of the blue filter
