Embodiment 1

[0031] Please refer to figure 2 and image 3 , figure 2 A top view of a color filter 101 provided by an embodiment of the present invention, image 3 for figure 2 A cross-sectional view along the line A-A` in the center. The color filter 101 includes a substrate 1; a black matrix 2 formed on the substrate 1; a pixel resin layer 3 formed on the black matrix 2; a protective layer 4 formed on the black matrix 2 and the pixel resin layer 3; The spacer 51 on the protective layer 4. The protection layer 4 has a slot B, and the slot B is disposed between any two adjacent spacers 51 .

[0032] Wherein, the substrate 1 is mainly made of glass, but may also be bendable transparent plastic, such as polyimide. If flexible transparent plastic is used as the material of the substrate 1, polyimide with excellent heat resistance can be used in consideration of the process of performing high-temperature deposition on the substrate 1 (polyimide can withstand high temperature).

Embodiment 2

[0041] Please refer to Figure 5 , Figure 5 It is a schematic structural diagram of a display panel 200 provided by the present invention. The display panel 200 includes an array substrate 201 , a color filter 202 opposite to the array substrate 201 , and a liquid crystal layer 203 between the array substrate 201 and the color filter 202 . Wherein, the color filter 202 is the color filter described in the above embodiments.

[0042] The display panel provided by this embodiment also has the above beneficial effects because the color filters of the above embodiments are used.

Embodiment 3

[0044] Please refer to Figure 6 , Figure 6It is a flow chart of the manufacturing method of the color filter 101 according to the first embodiment of the present invention. The manufacturing method of the color filter of the first embodiment of the present invention comprises the following steps:

[0045] First, a substrate 10 is provided;

[0046] Secondly, a black matrix layer is formed on the substrate 10, and a black matrix 2 is obtained by patterning;

[0047] Next, form a pixel resin layer 3 on the black matrix 2 and pattern it;

[0048] Again, a protective layer 4 is formed on the black matrix 2 and the pixel resin layer 3, and several slots B are formed on the protective layer 4;

[0049] Finally, several spacers 51 are prepared on the protective layer 4 .

[0050] It should be noted that the slot B is disposed between any two adjacent spacers.

[0051] It should be noted that the depth of the groove B is less than or equal to the thickness of the protective la...

Abstract

The present invention provides a color filter, a manufacturing method thereof, and a display panel, wherein the color filter includes: a substrate; a black matrix and a pixel resin layer formed on the substrate; a black matrix and a pixel resin layer formed on the black matrix and the A protective layer on the pixel resin layer; several spacers formed on the protective layer. Wherein, the protective layer has at least one slot, which is arranged between any two adjacent spacers. By providing grooves on the protective layer, it is possible to avoid the phenomenon that the bottoms of two adjacent spacers are bonded; thereby solving the problems of poor diffusivity of liquid crystals and easy occurrence of light leakage in the rubbing alignment process.

Description

technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to a color filter and a manufacturing method thereof, and also to a display panel including the color filter. Background technique [0002] At present, a thin film transistor liquid crystal display (Thin Film Transistor Liquid Crystal Display, TFT-LCD) is formed by combining a color filter and an array substrate, and the color filter is mainly used to provide colors for the TFT-LCD. With the continuous development of liquid crystal display technology, the number of pixels per inch (Pixels Per Inch, PPI) of TFT-LCD is increasing, and the pixel size is also getting smaller and smaller. In order for the TFT-LCD to achieve uniform surface pressure when subjected to vertical pressure, it is necessary to ensure that each sub-pixel corresponds to a photo spacer (PS). [0003] Please refer to figure 1 , figure 1 It is a schematic structural diagram of a color filter 100 i...
