Problems solved by technology

[0005] However, since both the common electrode line 3 and the voltage-dividing electrode 2 are made of metal materials, the voltage-dividing capacitance will affect the aperture ratio of the pixel unit.
Especially in the current development trend of higher resolution and smaller pixel unit area, the influence of the existing voltage dividing capacitor on the aperture ratio is more obvious

Abstract

The invention discloses an array substrate and a display device, belongs to the technical field of display, and aims to solve the technical problem that a voltage dividing capacitor influences the aperture opening ratio of a pixel unit. The array substrate comprises a plurality of pixel units, wherein the pixel units comprise main pixel regions, sub-pixel regions, first voltage dividing capacitors, driving scanning lines and voltage-dividing scanning lines; the first voltage dividing capacitors are formed by overlapping voltage-dividing electrodes with the driving scanning lines, or formed by overlapping the voltage-dividing electrodes with the voltage-dividing scanning lines. The array substrate can be applied to display devices such as liquid crystal televisions, liquid crystal displays, mobile phones and tablet computers.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to an array substrate and a display device. Background technique [0002] With the development of display technologies, liquid crystal displays have become the most common display devices. [0003] A Vertical Alignment (VA) liquid crystal display is a common liquid crystal display. At present, in order to improve the large viewing angle deviation phenomenon of the VA liquid crystal display, each pixel unit is divided into a main pixel area and a sub-pixel area, and a voltage dividing capacitor is added. [0004] Such as figure 1 and figure 2 As shown, the voltage dividing capacitor Cdown is formed by overlapping a part of the common electrode line (Com) 3 with the voltage dividing electrode 2 . In the display process, the first transistor T1 and the second transistor T2 are turned on by driving the scanning line (Gate1) 11, and the main pixel electrode (not shown in t...
