Problems solved by technology

Since the connection conductor and the pixel electrode are in the same layer, and the connection conductor needs to occupy a certain area on the passivation layer, the distribution and area of ​​the pixel electrode are limited. Therefore, the existence of the connection conductor will affect the pixel aperture ratio of the display device.

Abstract

The present application relates to an array substrate and a display device. The array substrate includes scanning lines perpendicular to each other and a common electrode of the second metal layer, and first pixels located on the same side of the same scanning line and on both sides of the common electrode of the same second metal layer. electrode and the second pixel electrode, the first pixel electrode has a first oblique side, the second pixel electrode has a second oblique side, the first oblique side and the second oblique side are arranged oppositely, and define the extension line of the first oblique side, the second oblique side The area surrounded by the extension line of the hypotenuse and the orthographic projection of the adjacent scanning line is the target area, and a connecting conductor is formed in the target area, and the connecting conductor is connected to the common electrode of the second metal layer on both sides of the insulating layer and the first electrode through a via hole. The metal layer has a common electrode, and the connecting conductor is parallel to the orthographic projections of the first oblique side, the second oblique side and adjacent scanning lines. In this application, the target area for setting the connecting conductor is first defined by the pixel electrode and the scanning line, and then the shape of the connecting conductor is designed to make the target area as small as possible, thereby increasing the aperture ratio of the pixel.

Description

technical field [0001] The present application relates to the display field, in particular to an array substrate and a display device. Background technique [0002] In the array substrate of the display device, each pixel electrode and the common electrode of the first metal layer form a storage capacitor. In order to make the signal of the common electrode of the first metal layer uniform, the common electrode of the second metal layer is usually set to be connected to the common electrode of each first metal layer. In order to make the common electrodes of the first metal layer communicate with each other. In the structure of the array substrate, the common electrodes of the first metal layer and the common electrodes of the second metal layer are at different levels, so they need to be connected through via holes. , insulating layer, second metal layer common electrode and passivation layer, and after forming a via hole through the passivation layer and the insulating la...
