Abstract

The invention relates to a pixel array substrate. The pixel array substrate comprises a substrate, a pixel array, first leads, first connecting pads, a first insulating layer, second leads and second connecting pads, wherein the substrate is provided with a display area and a non-display area; the pixel array is positioned in the display area; the first leads are electrically connected with the pixel array and are extended to the non-display area from the display area; the first connecting pads are positioned in the non-display area and each first connecting pad is electrically connected with the corresponding first lead; the first insulating layer covers the first leads and exposes the first connecting pads; the second leads are positioned over the insulating layer, are electrically connected with the pixel array and are extended to the non-display area from the display area; the second connecting pads are positioned in the non-display area and are arranged on the insulating layer, and each second connecting pad is electrically connected with the corresponding second lead; and particularly the distance between each first connecting pad and the adjacent second connecting pad in the horizontal direction is 10 to 20 mu m.

Description

technical field [0001] The invention relates to a pixel array substrate, a conductive structure and a display panel. Background technique [0002] Generally speaking, a liquid crystal display panel in a liquid crystal display is composed of a pixel array substrate, a color filter array substrate and a liquid crystal layer sandwiched between the two substrates. In the pixel array substrate, pads and leads are also provided in the non-display area to electrically connect the pixel array and the driving chip. [0003] With the development of displays, multimedia display functions and high-resolution requirements on small-sized display panels have become basic requirements. To meet the above requirements, a driver chip with a larger number of channels designed in the original chip size has also been developed. Therefore, in order to achieve rich multimedia display functions and high resolution in small-sized displays, and without increasing the number of driver chips to reduce...
