Problems solved by technology

All the above factors limit the spacer design, resulting in a small spacer compression for Oxide-TFT liquid crystal display panels, and there is a risk of gravity mura. At the same time, it will also cause an increase in the cost of spacer materials and a decrease in production capacity. Lowering the problem

Embodiment 1

[0068] In this embodiment, a color filter substrate is firstly provided, such as figure 1 As shown in , the color filter substrate mainly includes a first base substrate 11, a black matrix 12 and a color resist layer 17 disposed on the first base substrate 11, and spacers disposed on the black matrix 12; The spacers in this embodiment include a main spacer 14, a first auxiliary spacer 15 and a second auxiliary spacer 16, the main spacer 14 is arranged on the pillow layer 13, and the first auxiliary spacer 15 and the second auxiliary spacer 16 are directly arranged on the black matrix 12; wherein, the main spacer 14 is mainly used to prevent gravity Mura, the first auxiliary spacer 15 is mainly used to prevent Push (wiping) Mura, and the second Auxiliary spacer 16 is mainly used to prevent blackening Mura; Certainly, first auxiliary spacer 15 and second auxiliary spacer 16 may not be provided, or only first auxiliary spacer 15 and second auxiliary spacer may be provided. One o...

Embodiment 2

[0114] In this embodiment, a color filter substrate is firstly provided; Figure 7 As shown in , the color filter substrate mainly includes a first base substrate 11, a black matrix 12 and a color resist layer 17 disposed on the first base substrate 11, and spacers disposed on the black matrix 12; The spacers in this embodiment include a main spacer 14, a first auxiliary spacer 15 and a second auxiliary spacer 16; the main difference from Embodiment 1 is that in this embodiment, the pillow layer 13 is Multi-level stepped structure; for example, it can be a three-level stepped structure, the main spacer 14 is arranged on the highest step, the first auxiliary spacer 15 is arranged on the next highest step, and the second auxiliary spacer 16 is arranged on the lowest step; or, it can be a two-stage stepped structure, the main spacer 14 is arranged on the highest step, the first auxiliary spacer 15 is arranged on the lowest step, and the second auxiliary spacer The objects 16 are...

Embodiment 3

[0134] This embodiment provides a display device including the display panel provided in Embodiment 1 or Embodiment 2. Because in this display device, the compression amount of the spacer is increased by the pillow layer arranged on the black matrix, the risk of gravity Mura is reduced, and the picture display quality and the reliability of the display device are improved; in addition, because the pillow The thickness of the layer can be flexibly set according to requirements, so the compression amount of the spacer can be flexibly controlled without being limited by various limitations of the prior art, thereby improving the manufacturing efficiency of the display device and reducing the production cost. The above-mentioned display device may be any product or component with a display function such as a liquid crystal display panel, electronic paper, liquid crystal TV, liquid crystal display, digital photo frame, mobile phone, and tablet computer.

Abstract

The invention relates to the technical field of display, in particular to a color film substrate, a preparation method of the color film substrate, a display panel, a preparation method of the display panel and a display device. The color film substrate comprises a substrate body, a black matrix arranged on the substrate body and an insulation mat arranged above the black matrix, and a pillow layer is arranged between at least one portion of the insulation mat and the black matrix. Due to the facts that the pillow layer is formed on the black matrix and the insulation mat is arranged on the pillow layer, the compression amount of the insulation mat is increased, the risk of the gravity Mura is reduced, the image display quality and the reliability of the display device are improved, in addition, the thickness of the pillow layer can be flexibly set according to the requirement, the continuous changes of the thickness of the pillow layer are achieved, the compression amount of the insulation mat can be flexibly controlled, and not be limited by various kinds of limitations in the prior art, and the strong technological support can be provided for improving the preparation efficiency of the display device and reducing the production cost.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a color filter substrate and a preparation method thereof, a display panel using the color filter substrate, a preparation method thereof, and a display device using the display panel. Background technique [0002] Compared with traditional cathode ray tube display devices, flat panel display devices have the advantages of thinness, low driving voltage, no flickering and long service life; flat panel display devices are divided into active light-emitting display devices and passive light-emitting display devices; for example, thin film transistor liquid crystal The display device (Thin Film Transistor-Liquid Crystal Display, TFT-LCD) is a passive light-emitting display device, which is widely used in TVs, In electronic products such as mobile phones and display devices, the flat panel display field has already occupied a dominant position. [0003] The liquid crystal di...
