Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0038] An embodiment of the present invention provides a method for preparing a display substrate, such as Figure 5 shown, including:

[0039] S100, such as Image 6 As shown, a pattern layer 60 is formed on a substrate 40 .

[0040] It should be understood that the pattern layer 60 includes convex portions and concave portions (or hollowed out portions), and the surface of the pattern layer 60 away from the substrate 40 is uneven.

[0041] Wherein, the pa...

Abstract

The embodiment of the invention provides a preparation method of a display substrate, the display substrate and a display device, and relates to the technical field of display. The problem of excessive thickness of a flat layer can be solved. The preparation method of the display substrate comprises the following steps: forming a pattern layer on the substrate; forming a flat layer on the patternlayer, wherein the material of the flat layer comprises a host material, and a hydrophilic material and a hydrophobic material, which are doped in the host material; treating the flat layer, so that the host material reacts with the hydrophilic material to form a hydrophilic polymer, and the host material reacts with the hydrophobic material to form a hydrophobic polymer, and the flat layer is layered to form a first sub-flat layer and a second sub-flat layer, which are laminated; the second sub-flat layer is adjacent to the substrate with respect to the first sub-flat layer, the material of the first sub-flat layer comprises the hydrophobic polymer, and the material of the second sub-flat layer comprises the hydrophilic polymer; and cleaning the flat layer with a cleaning solution, wherein the cleaning solution reacts with the hydrophobic polymer to remove some or all of the first sub-flat layer.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for preparing a display substrate, a display substrate and a display device. Background technique [0002] With the rapid development of display technology, the black matrix pattern and the color photoresist pattern in the current display panel may be disposed on different substrates, or the display panel only includes the black matrix pattern and does not include the color photoresist pattern. For example, a Dual Cell (double-layer display panel) display device consists of such as figure 1 The Normal Cell1 shown (conventional liquid crystal display panel) and such as figure 2 The Mono Cell 2 (unconventional liquid crystal display panel) stacked composition shown. [0003] Wherein, Normal Cell1 is used for normal color picture display, and Normal Cell1 comprises array substrate 10, the liquid crystal layer 30 that is arranged between array substrate 10 and box substr...
