Embodiment 1

[0032] like Figure 1-3 As shown, this embodiment provides a method for preparing a color filter substrate, which is characterized in that it includes:

[0033] The step of performing the first ultraviolet light irradiation and heating treatment on the functional layer on the light-emitting side sequentially formed on the substrate 1 through a patterning process, for removing the decomposition products of organic materials in the functional layer due to ultraviolet irradiation;

[0034] A step of forming an alignment layer 7 on the functional layer;

[0035] A step of performing alignment on the alignment layer 7 by irradiating ultraviolet light for the second time.

[0036] In this embodiment, before forming the alignment layer 7, the functional layer on the light-emitting side of the color filter substrate is irradiated with ultraviolet light and heat-treated for the first time, so that the decomposition products of organic materials in the functional layer due to ultraviol...

Embodiment 2

[0059] This embodiment provides a display panel, including a color filter substrate, and the color filter substrate is prepared by using the above-mentioned method for preparing a color filter substrate.

Embodiment 3

[0061] This embodiment provides a display device including the above-mentioned display panel.

Abstract

The invention provides a method for preparing a color film substrate, a display panel, and a display device, which belong to the field of display technology, and can solve the problem of aligning an alignment layer with ultraviolet light in the existing method for preparing a color film substrate, a display panel, and a display device. At this time, the organic material functional layer prepared before the alignment layer degrades and is gradually released into the liquid crystal layer to produce foreign matter bright spots. The preparation method of the color filter substrate, the display panel, and the display device of the present invention can make the Organic materials are volatilized and removed due to the decomposition of ultraviolet radiation, and will not be gradually released into the liquid crystal layer to form foreign matter after the alignment layer is coated and irradiated by ultraviolet radiation when the array substrate and the color filter substrate are aligned. The bright spots affect the display quality of the display panel.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a preparation method of a color filter substrate, a display panel, and a display device. Background technique [0002] In recent years, with the popularization of digital TV, the traditional "cathode ray picture tube display has a tendency to be replaced by a new generation of display technology due to its difficulty in digitization, large size, heavy weight, and radiation. The representative display technology There are plasma display, organic electro-laser display, liquid crystal display, etc. Among them, liquid crystal display has begun to be widely popularized due to its advantages of light weight, thin volume, no radiation, low power consumption, and good display effect, and has become a mainstream product. [0003] The liquid crystal display panel includes an array substrate, a color filter substrate, and a liquid crystal layer arranged between the display subs...
