Abstract

The invention provides an array substrate and a manufacturing method thereof as well as a display device. The manufacturing method comprises the following steps: forming a grilling insulation layer; forming a data cable figure on the grilling insulation layer; forming a pixel electrode figure on the structure of the formed data cable figure; forming a passivation layer on the data cable figure and the grilling insulation layer; forming a slot in the passivation layer, wherein the slot is formed between the supposed pixel electrode figure and the supposed data cable figure; etching the structure of the formed passivation layer to eliminate the data cable figure formed under the slot; forming a common electrode figure on the passivation layer. According to the manufacturing method, the data cable figure can be prevented from being connected with the pixel electrode figure.

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] Advanced Super Dimension Switch (ADSDS, ADS for short) technology is to form a multi-dimensional electric field through the electric field generated by the edge of the slit electrode in the same plane and the electric field generated between the slit electrode layer and the plate electrode layer. All oriented liquid crystal molecules between the slit electrodes in the liquid crystal cell and directly above the electrodes can be rotated, thereby improving the working efficiency of the liquid crystal and increasing the light transmission efficiency. Advanced ultra-dimensional field conversion technology can improve the thin film field effect transistor liquid crystal display ( Thin Film Transistor-Liquid Crystal Display, TFT-LCD) product picture quality, with high resolu...
