Problems solved by technology

Due to the chemical vapor deposition, the surface of the gate insulating layer and the surface of the active layer are easy to form a particle surface, which easily leads to insufficient contact between the source and the drain and the active layer, so that the source and the drain are in contact with the active layer. The contact barrier between the source layers increases or the contact between the two is unstable; or, the grainy surface will directly cause the source, drain and data lines to form small gaps in their film layers during metal sputtering,

[0059] Example 2:

[0060] This embodiment provides an array substrate. The difference from embodiment 1 is that, on the basis of embodiment 1, the display area of ​​the array substrate is further provided with a spare electrode, and the body electrode also includes a spare electrode, a substrate electrode and a display electrode (Ie, the pixel electrode) is formed with the same material and in the same patterning process. That is, the substrate electrode and the pixel electrode under the spare electrode are formed in the same layer of the array substrate.

[0061] Wherein, the spare electrode and the data line use the same material and are formed on the same layer in the same patterning process. The spare electrode is generally used to repair a short-circuited or open data line.

[0062] The other structures of the array substrate in this embodiment are the same as those in Embodiment 1, and will not be repeated.

Abstract

The invention provides an array substrate, a method for manufacturing the same and a display device. The array substrate comprises a substrate and a plurality of electrode structures. The electrode structures are arranged on the upper side of the substrate and comprise body electrodes and substrate electrodes, the body electrodes are made of metal materials, and the substrate electrodes are made of transparent metal oxide materials; the substrate electrodes are positioned under the body electrodes and are partially or completely overlapped with the body electrodes in orthographic projection directions; the substrate electrodes are electrically connected with the body electrodes. The array substrate, the method and the display device have the advantages that the substrate electrodes are arranged under the body electrodes (such as metal lines, source electrodes, drain electrodes, standby electrodes and signal input electrodes) made of the metal materials, so that the body electrodes can be in close contact with a gate insulation layer or active layers, small notches cannot be easily formed inside the body electrodes, open circuit of the body electrodes can be prevented, and the quality of the array substrate can be guaranteed; the display quality of the display device with the array substrate further can be guaranteed.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to an array substrate, a preparation method thereof, and a display device. Background technique [0002] Liquid Crystal Display (LCD: Liquid Crystal Display) has become the mainstream product in the current flat panel display due to its small size, low power consumption, and no radiation. At present, with the continuous upgrading of liquid crystal display technology, high-quality liquid crystal displays have become the unanimous goal pursued by various manufacturers. [0003] Array substrate is an important part of liquid crystal display and also a key component for display. During the preparation process of the array substrate, some objective defects in the preparation process often lead to some quality problems of the array substrate. [0004] For example, for the HADS (High Advanced Super Dimension Switch, High Aperture Ratio Advanced Super Dimension Field Switchin...
