Abstract

The invention discloses a thin film transistor array substrate, a manufacturing method thereof and a displaying device. The method comprises the steps that a drain electrode and a source electrode are formed on a substrate; a planarization layer with a groove is formed; a touch metal layer with the upper surface flush with the upper surface of the planarization layer is formed; and a first insulation layer, a common electrode layer, a second insulation layer and a pixel electrode layer are formed. The surface concave-convex degree of the thin film transistor array substrate is improved, the adhesiveness between a PI film and the array substrate is improved, and the displaying performance of the displaying device is improved.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to a thin film transistor array substrate and a manufacturing method thereof, and also relates to a display device with the thin film transistor array substrate. Background technique [0002] The manufacture of a general TFT-LCD (Thin Film Transistor-Liquid Crystal Display, Thin Film Transistor-Liquid Crystal Display) is completed through the following three steps: TFT array substrate manufacturing steps, CF (color filter plate) substrate manufacturing steps, and liquid crystal formation. Box (Cell) manufacturing steps. Among them, when forming a liquid crystal cell, the alignment of liquid crystal molecules is mainly carried out by coating PI (polyimide) on the TFT side substrate (ie, TFT array substrate) and the CF side substrate respectively, so that the liquid crystal molecules are in a natural state. It is at a specific angle, and after that liquid cryst...
