Embodiment 1

[0070] figure 1 It is a schematic flowchart of the manufacturing method of the array substrate provided by Embodiment 1 of the present invention, figure 2 A schematic structural view of the array substrate provided by the present invention, image 3 Another structural schematic diagram of the array substrate provided by the present invention, Figure 4 Another structural schematic diagram of the array substrate provided by the present invention;

[0071] This embodiment provides a method for manufacturing an array substrate, specifically an array substrate (color filter on array, COA for short) provided with a color filter, that is, a COA array substrate. In this embodiment, the array substrate used The spacer (PS) is formed simultaneously in the process of forming the color filter on the color filter, thereby avoiding setting up the PS process independently to form the PS. The number of steps in the process is reduced, thereby reducing production costs.

Abstract

The invention discloses an array substrate, a making method thereof and a display panel. The method comprises the steps that a thin film transistor layer is formed on a non-pixel area on the substrate; color filter layers are formed on a pixel area of the substrate and the thin film transistor layer, the color filter layer located on the pixel area forms multiple color resistance units arranged inan array, and the color filter layer located on the thin film transistor layer forms a spacer; a pixel electrode layer covers the color resistance units, and drain electrodes of the pixel electrode layer and the thin film transistor layer are connected through via holes. According to the making method of the array substrate, the purpose of omitting the PS process is achieved, and the technical problems that by means of existing PS preparation, the making processes of the array substrate or a color film substrate are increased, and the production cost is increased are solved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a manufacturing method thereof, and a display panel. Background technique [0002] Liquid crystal display (Liquid Crystal Display, LCD) is the most widely used display product on the market at present, and the liquid crystal display mainly includes a liquid crystal display panel and a backlight module. The liquid crystal between the (array) substrate and the color filter (color filter, CF for short) substrate, wherein, in order to maintain the distance between the two substrates, a spacer (photospacer, PS for short) is arranged between the CF substrate and the array substrate. [0003] At present, there are mainly two ways to arrange the spacer (PS): one is to form the PS on the side of the CF substrate facing the array substrate, specifically, to form the PS on the common electrode of the CF substrate; the other is to form the spacer on the array sub...
