Abstract

The invention discloses an array substrate, a manufacture method of the array substrate and a display device and relates to the display field. The using times of a picture composition process in the array substrate manufacture process can be decreased, accordingly the manufacture cost if effectively reduced, and the yield is improved. The array substrate comprises a substrate body, a grid electrode, a grid insulating layer, an active layer, a source electrode, a drain electrode and an insulation protecting layer, wherein the grid electrode, the grid insulating layer, the active layer, the source electrode, the drain electrode and the insulation protecting layer are sequentially arranged on the substrate body. A pixel electrode, a public electrode, a first lead wire hole connected with the pixel electrode and the drain electrode and a second lead wire hole connected with the public electrode and a public electrode wire are further arranged on the substrate body, the pixel electrode is arranged on the substrate body, and the grid electrode is directly arranged on a transparent conducting layer which is arranged on the same layer together with the pixel electrode. The pixel electrode is connected with the drain electrode through a first metal connecting layer arranged in the first lead wire hole, and the first metal connecting layer and the grid electrode are arranged on the same layer.

Description

technical field [0001] The present invention relates to the display field, in particular to an array substrate, a manufacturing method thereof, and a display device. Background technique [0002] Advanced-Super Dimensional Switching (abbreviation: ADS) forms a multi-dimensional electric field through the parallel electric field generated by the edge of the pixel electrode or the common electrode in the same plane and the vertical electric field generated between the pixel electrode and the common electrode, so that the liquid crystal cell All alignment liquid crystal molecules between the inner pixel electrodes or the common electrodes, and directly above the pixel electrodes or the common electrodes can produce rotation conversion, thereby improving the working efficiency of the plane alignment liquid crystal and increasing the light transmission efficiency. Advanced ultra-dimensional field switching technology can improve the picture quality of TFT-LCD, and has the advanta...
