Abstract

The invention provides an array substrate and a manufacturing method thereof, a display panel, and a display device. The array substrate includes insulating layers, a second common electrode line formed in the line area of a gate drive circuit, a conductive connection part formed in the gate drive circuit area and a first common electrode line area, the second common electrode line is connected with the conductive connection part, the insulating layers are arranged between the second common electrode line and the gate drive circuit line, between the conductive connection part and the gate drive circuit, and between the conductive connection part and the first common electrode line, the insulating layer between the conductive connection part and the first common electrode line is provided with a through hole, and the conductive connection part is connected with the first common electrode line via the through hole. The array substrate facilitates the edge narrowing of the corresponding display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate and a manufacturing method thereof, a display panel and a display device. Background technique [0002] GOA ((Gate Driver On Array, gate drive circuit on the array substrate) [0003] Technology Compared with traditional Chip On Flex / Film (COF) and directly bonded on glass (Chip OnGlass, COG) processes, GOA technology can not only save costs, but also the panel can achieve a symmetrical and beautiful design on both sides. The main feature of the technology is that it relies on the continuous triggering of the GOA unit to realize its shift register function, which saves the bonding (Bonding) area of ​​the gate integrated circuit (GateIC) and the Fan-out wiring space, and realizes the design of a narrow frame; at the same time, due to The Bonding process in the Gate direction can be omitted, which is also beneficial to the improvement of production capa...
