Problems solved by technology

After the array substrate and the matching substrate are boxed, the end of the spacer is in contact with the array substrate, and the contact position is at the highest position of the array substrate. When the array substrate is squeezed or stamped, the spacer will slide down to a lower position. Low position, and it is difficult to return to the original position, therefore, it will cause the array substrate to be misaligned, thereby causing light leakage

Abstract

An embodiment of the invention provides an array substrate and a preparation method and a display device thereof and relates to the technical field of displaying. The problem of position offset of a shock insulator and the array substrate can be solved, and therefore, light leakage is improved. The array substrate comprises a substrate, a switch unit arranged on the substrate, a passivating layer arranged on the substrate, and a spacer arranged on the passivating layer. The spacer corresponds with the switch unit. The method is used for manufacturing of the array substrate and the display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a preparation method thereof, and a display device. Background technique [0002] In the structure of a Thin Film Transistor-Liquid Crystal Display (TFT-LCD for short), spacers are essential in order to form a liquid crystal cell thickness required for optical rotation of liquid crystals. [0003] At present, the spacers are all located on the box substrate, that is, by coating an organic resin layer on the box substrate, and then forming a spacer pattern with a specific height through a photolithography process. After the array substrate and the matching substrate are boxed, the end of the spacer is in contact with the array substrate, and the contact position is at the highest position of the array substrate. When the array substrate is squeezed or stamped, the spacer will slide down to a lower position. low position, and it is difficult to return ...
