Embodiment Construction

[0026] Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. In the various figures, identical elements are indicated with similar reference numerals. For the sake of clarity, various parts in the drawings have not been drawn to scale. Also, some well-known parts may not be shown in the drawings.

[0027] In the following, many specific details of the present invention are described, such as structures, materials, dimensions, processes and techniques of components, for a clearer understanding of the present invention. However, the invention may be practiced without these specific details, as will be understood by those skilled in the art.

[0028] It should be understood that when describing the structure of a component, when a layer or a region is referred to as being “on” or “over” another layer or another region, it may mean being directly on another layer or another region, or Other layers or regions are also in...

Abstract

The invention discloses an array substrate, a manufacturing method thereof and a display device. The array substrate includes: a base substrate; a plurality of thin film transistors arranged on the base substrate in a transistor array; a plurality of pixel electrodes located above the plurality of thin film transistors, a plurality of pixel electrodes and a plurality of thin film transistors The drain electrodes are respectively connected to each other; and the first common electrode and the second common electrode are electrically connected to each other by using an interconnection structure. The interconnection structure includes: an interconnection region located above the first common electrode and the second common electrode; a second via hole connecting the second common electrode to the interconnection region; and a third A via hole is used to connect the first common electrode to the interconnection region. The electrical connection between the first common electrode and the second common electrode can increase the loading speed of the common voltage and improve the uniformity of the common voltage.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to an array substrate, a manufacturing method thereof, and a display device. Background technique [0002] The liquid crystal display device uses the voltage difference between the pixel electrode and the common electrode to change the rotation angle of the liquid crystal molecules, thereby changing the light transmittance when the backlight passes through, and realizing grayscale display. [0003] figure 1 A top view of an array substrate according to the prior art is shown. Such as figure 1 As shown, the array substrate 100 includes first to fourth metal layers, a semiconductor layer, and a plurality of passivation layers stacked on the base substrate 101 . The first metal layer is used to form the gate line 110, the second metal layer is used to form the source line 120, the drain line 160 and the second common electrode 180, the third metal layer is used to ...
