Abstract

The invention discloses a TFT substrate and a manufacturing method thereof, and a display device, and belongs to the technical field of liquid crystal display. The TFT substrate comprises a substrate body on which a common electrode metal is formed; a grid insulation layer is formed on the substrate with the common electrode metal; a passivation layer is formed on the substrate with the grid insulation layer; a passivation layer area corresponding to the common electrode metal is a common electrode metal area; a current stopping groove is formed on the common electrode metal area. According to the TFT substrate, the current stopping groove is formed in the common electrode metal area to stop PI solution, so that the problems of the PI solution in the AA area is reduced and cannot be uniformly distributed, a formed alignment film is poor in thickness uniformity and the LCD easily suffers from adverse clouding during display, can be avoided; the loss speed of the PI solution can be reduced; the PI solution in the AA area can be uniformly distributed, the formed alignment film is high in uniformity, adverse clouding is avoided, and as a result, the display performance of the LCD can be improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a TFT substrate, a manufacturing method thereof, and a display device. Background technique [0002] Liquid crystal display (English: Liquid Crystal Display, referred to as: LCD) controls the light penetrating the liquid crystal layer by controlling the rotation direction and rotation angle of the liquid crystal molecules, thereby displaying images of various grayscales. It has high picture quality, small size, Light weight and other advantages, widely used in mobile phones, notebook computers, televisions and monitors and other products. Usually, an alignment film is formed on a thin film field effect transistor (English: Thin Film Transistor, TFT for short) substrate in the LCD, and liquid crystal molecules are arranged on the alignment film. [0003] The TFT substrate 01 generally includes: a base substrate, a common electrode (English: Com) metal is formed on ...
