A kind of color filter and its manufacturing method, display device

Abstract

The invention discloses a color filter, a manufacture method thereof and a display device. The color filter comprises a substrate, a black matrix, a first color resin layer, a second color resin layer, a third color resin layer and PSs (post spacer), wherein the black matrix covers the substrate, the first color resin layer covers a first area of the black matrix, the second color resin layer covers a second area of the black matrix, the third color resin layer covers a third area of the black matrix, the PSs are respectively positioned on the designated positions of the first color resin layer, the second color resin layer and the third color resin layer, and the three PSs have the same height and the same bottom surface diameter. Through the technical scheme, a flattening layer does not need to be formed on each color resin layer, the color filter meeting the technological requirements can be manufactured by only controlling the thicknesses of the color resin layers in different colors, and the height difference of the Main PS and the Sub PS do not need to be controlled, so the manufacture flow is simplified, and the manufacture cost is effectively reduced.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a color filter, a manufacturing method thereof, and a display device. Background technique [0002] TFT-LCD (ThinFilmTransistorLiquidCrystalDisplay, Thin Film Transistor Liquid Crystal Display) has been widely used for its small size, low power consumption, and no radiation. LTPS (Low Temperature Poly-silicon; low temperature polysilicon) thin film transistor liquid crystal display (LTPS-TFTLD) is a kind of TFT-LCD, which has the advantages of high resolution, fast response speed, high brightness and high aperture ratio. Moreover, since the silicon crystal arrangement of LTPS-TFTLD is more orderly than that of a-Si, its electron mobility is faster, and the peripheral drive circuit can be directly fabricated on the panel, which can reduce the external contact points of components, increase reliability and maintain It is simpler, shortens the assembly process time and reduces...
