Array substrate, manufacturing method thereof and display device

Abstract

The invention provides an array substrate, a manufacturing method of the array substrate and a display device and relates to the technical field of liquid crystal display panel manufacture. The problems that a drain electrode and a common electrode layer of an existing high-definition display device are communicated, so that the common electrode layer and a pixel electrode layer are communicated, the sub-pixel function can not be achieved normally, and dark spots are generated are solved. Product quality is guaranteed, the waste of production materials is reduced, and production cost is reduced. The array substrate comprises a substrate body, a source electrode, a drain electrode, an organic resin layer and a common electrode layer formed on the organic resin layer. A first passing hole is formed in the organic resin layer, an isolation layer is arranged on the source electrode and the drain electrode and covers the substrate body, and the isolation layer is completely covered with the organic resin layer. A second passing hole communicated with the first passing hole to expose part of the drain electrode is formed in the isolation layer, wherein the size of the firs passing hole is larger than that of the first passing hole. The array substrate, the manufacturing method of the array substrate and the display device are applied to the technical field of display panel manufacture.

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] With the continuous development of liquid crystal display technology, the resolution requirements of display devices are getting higher and higher, and currently full high-definition display has become the mainstream. In order to realize full high-definition display devices, such as figure 1 As shown in , an organic resin layer 8 needs to be formed on the source electrode 6 and the drain electrode 7 to reduce the power consumption of the array substrate and increase the aperture ratio. At the same time, it is necessary to make a via hole to connect the drain electrode to the pixel electrode layer, and finally generate a voltage difference between the common electrode layer and the pixel electrode layer to ensure the normal display of the sub-pixel function.
