Abstract

The invention provides a method for manufacturing an array substrate, the array substrate and a display device and belongs to the field of liquid crystal display. The array substrate comprises a pixel electrode provided with a segment difference portion, wherein parts of the pixel electrode located on two sides of the segment difference portion are communicated through conducting layers and through via holes, and the conducting layers and the pixel electrode are located on different layers. Shutoff of a pixel electrode layer signal caused by fault of the pixel electrode can be avoided.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a method for manufacturing an array substrate, the array substrate and a display device. Background technique [0002] Thin film transistor liquid crystal display (TFT-LCD) has the characteristics of small size, low power consumption, and no radiation, and occupies a dominant position in the current flat panel display market. Among them, ADvanced Super Dimension Switch (ADS for short) uses 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 to form a multi-dimensional electric field, so that the liquid crystal All oriented liquid crystal molecules between the slit electrodes in the cell and directly above the electrodes can be rotated, thereby improving the working efficiency of the liquid crystal and increasing the light transmission efficiency. Adva...
