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, such as structures, materials, dimensions, processes and techniques of components, are described 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 comprises an underlayer substrate, multiple thin film transistors located on the underlayer substrate, multiple pixel electrodes located above the thin film transistors, a first common electrode and a second common electrode. The thin film transistors are arranged into a transistorarray. The pixel electrodes are connected with drain electrodes of the thin film transistors respectively. The first common electrode and the second common electrode are electrically connected throughan interconnecting structure. The interconnecting structure comprises an interconnecting region located above the first common electrode and the second common electrode, a second via hole for enabling the second common electrode to be connected to the interconnecting region, and a third via hole for enabling the first common electrode to be connected to the interconnecting region. The first common electrode and the second common electrode are electrically connected, so that the loading speed of common voltages is increased, and the uniformity of the common voltages is improved.

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 gray scale 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...
