Abstract

The invention relates to the field of manufacture of liquid crystal display devices, in particular to an array substrate and a manufacture method thereof, aiming to solve the problem that the traditional manufacture process of a TFT-LCD (Thin Film Transistor Liquid Crystal Display) based on an ADS (Advanced Super Dimension Switch) structure is complex and is low in efficiency. According to the embodiment of the invention, each pixel region of the array substrate comprises a drain electrode, a source electrode, a pixel electrode in lap joint with the drain electrode, an active layer located on the drain electrode, the source electrode and the pixel electrode, a grid insulating layer located on the active layer, a grid electrode and a public electrode, wherein the drain electrode and the source electrode are located on an underlayer substrate, the pixel electrode is made of a single-walled carbon nanotube material, the grid electrode and the public electrode are located on the grid insulating layer, and the public electrode has a slit-shaped structure. According to the embodiment of the invention, the array substrate can be prepared by adopting layout processes three times, so that the manufacture process is simplified, the manufacture efficiency is improved and the manufacture cost is reduced.

Description

technical field [0001] The invention relates to the field of manufacturing liquid crystal display devices, in particular to an array substrate and a manufacturing method thereof. Background technique [0002] Liquid Crystal Display (LCD) has the characteristics of small size, light weight, low power consumption, low radiation and low manufacturing cost, and has been widely used in various electronic devices, such as monitors, TVs, mobile phones, digital cameras, etc. digital electronics. Among them, TFT-LCD (Thin Film Transistor Liquid Crystal Display, Thin Film Transistor Liquid Crystal Display) is a main flat panel display device (FPD, Flat Panel Display). [0003] According to the direction of the electric field driving the liquid crystal, TFT-LCD is divided into vertical electric field type, horizontal electric field type and multi-dimensional electric field type. Among them, the vertical electric field type TFT-LCD needs to form pixel electrodes on the array substrate...
