Abstract

The invention provides an array substrate and manufacturing method thereof and display device, relates to the technical field of display, and can solve the problem of low light transmissivity when an array substrate of a comb-shaped electrode structure is adopted. The manufacturing method of the array substrate includes the steps of: forming a first conductive thin film and a passivation layer thin film on a lining substrate in sequence; adopting a one-time composition process, removing the passivation layer thin film and the first conductive thin film except a to-be-formed first electrode area, and forming a graph of a passivation layer and a graph of a first electrode; forming a second conductive thin film on the lining substrate having the graph of the passivation layer and the graph of the first electrode; and adopting the one-time picture composition process, removing the second conductive thin film except a to-be-form second electrode area, and forming a graph of a second electrode. The manufacturing method of the abovementioned array substrate is used for manufacturing the array substrate.

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 device. Background technique

[0002] Liquid crystal display device is currently the most mainstream display device in the field of display technology. According to the different arrangement of liquid crystal molecules, liquid crystal display devices can be divided into TN (Twisted Nematic, twisted nematic) type, IPS (In-Plane Switching, in-plane switching) Type, VA (VerticalAlignment, vertical orientation) type and other types. Among them, the IPS type liquid crystal display device has the advantages of wide viewing angle, fast response speed, accurate color reproduction, etc., and has received extensive attention in the field.

[0003] The array substrate of the IPS liquid crystal display device has various structures, and the manufacturing process of the array substrate of one structure requires four p...
