Problems solved by technology

The increase in the thickness of the color film will not only increase the cost, but also reduce the light transmittance of the entire display device, which in turn will increase the power consumption of the panel, which is not conducive to energy saving and environmental protection.

Embodiment Construction

[0030] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0031] see figure 2 , see also Figure 3-5 , the present invention provides a color filter substrate, comprising a base substrate 10, a black matrix 20 disposed on the base substrate 10, and several A color-resisting block 30, the color-resisting block 30 includes a porous support layer 40 and a color-resisting material dispersed in the porous supporting layer 40; the color-resisting material includes pigment molecules; the porous supporting layer 40 is provided with a plurality of pores , the size of the pores is slightly larger than the size of the pigment molecules.

[0032] In addition to pigment molecules, the color resist material also includes other components such as dispersant and resin, which are used to disperse the pigment. The...

Abstract

The invention provides a colored membrane substrate and a display device. The colored membrane substrate comprises a lining substrate, black matrixes and a plurality of color-resistant blocks, wherein the black matrixes are arranged on the lining substrate; the color-resistant blocks are arranged on the lining substrate and are partitioned by the black matrixes; the color-resistant blocks comprise porous support layers and a color-resistant material dispersed in the porous support layers; the color-resistant material comprises pigment molecules; a plurality of pores are formed in the porous support layers; and the size of each pore is greater than that of each pigment molecule. Therefore, dispersion and support of the pigment molecules can be effectively achieved, so that the contents of non-pigment components such as a dispersing agent and resin in the color-resistant material are reduced, the content of pigment components is increased, the light filtering capacity of unit membrane thickness of the color-resistant blocks is increased, the purpose of thinning the colored membrane substrate is achieved, and relatively high pixel density can be achieved. The display device provided by the invention comprises the colored membrane substrate and has the advantages of wide color gamut, small thickness, high brightness and the like.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a color filter substrate and a display device. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] Most of the liquid crystal displays currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates. There are many vertical and horizontal small wires between the two glass substrates. The direction of the liquid crystal molecules is cont...
