Abstract

The invention discloses an array substrate, a display device and a manufacturing method of the array substrate, relating to the technical field of liquid crystal display. According to the invention, the resistance of a common electrode is reduced, and the uniformity of the voltage of the common electrode is enhanced. The array substrate comprises a plurality of pixel units, wherein each pixel unit comprises a pixel electrode, a common electrode and a metal wire, and the metal wire is positioned on a layer different from a common electrode layer; an insulating layer is arranged between the metal wire layer and the common electrode layer, and the insulating layer is provided with a plurality of through holes in a metal wire area; and the metal wire is connected with the common electrode through the through holes. The display device comprises the array substrate.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to an array substrate, a display device and a manufacturing method of the array substrate. Background technique [0002] In the current liquid crystal display, there are many situations for setting the common electrode in the panel, one of which is to set the common electrode in the color filter substrate, and the other is to set the common electrode and the pixel electrode on the array substrate. , such as Advanced-Super Dimensional Switching (ADS for short) technology. ADS 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, so that all oriented liquid crystal molecules between the slit electrodes and directly above the electrodes in the liquid crystal cell are aligned. ...
