Abstract

The invention discloses an array substrate. The array substrate includes a display area and a peripheral area adjacent to the display area. The display area includes a plurality of pixel units, and each of the pixel units is provided with a thin film transistor and a pixel electrode. , wherein the drain of the thin film transistor is in direct contact with the pixel electrode. The invention also discloses a display device including the array substrate and a manufacturing method of the array substrate. In the array substrate provided by the present invention, the pixel electrode is in direct contact with the thin film transistor, so that no contact resistance occurs, and the electric field between the common electrode and the pixel electrode can be evenly distributed.

Description

Technical field [0001] The present invention relates to liquid crystal display technology, in particular to an array substrate, a manufacturing method of the array substrate, and a display device including the array substrate. Background technique [0002] The array substrate is divided into a display area and a peripheral area adjacent to the display area. The display area is divided into a plurality of pixel units. Each pixel unit is provided with a thin film transistor and a pixel electrode. In the pixel unit, the drain of the thin film transistor and the pixel electrode are electrically connected through a via hole. However, when the metal in the via hole is in contact with the pixel electrode, a larger contact resistance will be generated, resulting in uneven charge distribution between the common electrode and the pixel electrode. [0003] Therefore, how to make the charge uniformly distributed between the common electrode and the pixel electrode becomes a technical problem ...
