Embodiment Construction

[0042] 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 creative efforts fall within the protection scope of the present invention.

[0043] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0044] In addition, the descriptions i...

Abstract

The invention discloses an array substrate and a manufacturing method thereof, a display panel and a display device. The array substrate comprises a substrate base plate, a color resistance layer, anorganic insulating film layer, a pixel electrode layer and a liquid crystal guide film layer, wherein the color resistance layer, the organic insulating film layer, the pixel electrode layer and the liquid crystal guide film layer are sequentially arranged on the substrate base plate. An ion barrier layer is further arranged between the organic insulating film layer and the liquid crystal guide film layer so as to prevent ions from reaching the liquid crystal guide film layer. By means of the mode, a problem of residual images of the panel can be avoided, and display quality is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate and a preparation method thereof, a display panel and a display device. Background technique [0002] COA (Color Filter on Array) technology is a technology in which a color filter layer is prepared on a thin film transistor to form a color filter. Because the liquid crystal display panel of the COA panel does not have the alignment problem between the color filter substrate and the array substrate, it can reduce the difficulty of the box alignment process in the display panel manufacturing process and avoid errors in the box alignment; at the same time, the COA panel has low parasitic capacitance, The advantages of high aperture ratio and relatively flat are widely used in large-size high-definition (8K / 16K) products. [0003] In the prior art, the color-resist layer will generate some impurity ions to diffuse toward the liquid crystal layer, because...
