Pixel structure and display device

Abstract

The present invention provides a pixel structure and a display device, wherein the pixel structure includes a base substrate, and a common electrode, a gate insulating layer, a passivation layer and a pixel electrode sequentially stacked on the base substrate, and also includes: A conductive electrode between the layer and the gate insulating layer, the conductive electrode is located in the overlapping area of ​​the pixel electrode and the common electrode, and is electrically connected with the pixel electrode to form a storage capacitor with the common electrode. The conductive electrode and the pixel electrode of the pixel structure above form a storage capacitor together with the common electrode, and there is only a layer of gate insulating layer between the conductive electrode and the common electrode, which reduces the distance between the two parts that constitute the storage capacitor. Therefore, the storage capacitance is increased, and the display performance of the display device is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel structure and a display device. Background technique [0002] The main pixel area of ​​the liquid crystal display device includes a plurality of pixel units arranged in an array, and each pixel unit includes three sub-pixels of red, green and blue. [0003] According to different driving methods, the pixel structure of the liquid crystal display device can be divided into: single gate driving, double gate driving, triple gate driving and other types. Among them, the pixel structure of double gate driving is: sub-pixels of three colors are driven by two gates together, in this pixel structure, two adjacent sub-pixels share the same data line, so the number of data driving chips can be saved , to reduce manufacturing costs. [0004] However, in the pixel structure driven by double gates, there are two layers of film layers, the gate insulating layer and the passi...

Problems solved by technology

[0004] However, in the pixel structure driven by double gates, there are two layers of film layers, the gate insulating layer and the passivation layer, between the common electrode and the pixel electrode, resulting in a relatively long distance between the common electrode and the pixel electrode, and the memory formed by the two The capacitance is small, which affects the display performance of the display device
