The array substrate comprises a display area 01 and a wiring area 02 located around the display area 01, wherein signal wires 03 and a silver dispensing part 04 are arranged in the wiring area 02. Because the insulating layer on the upper portion of the signal line 03 is easily scratched and damaged, the signal line 03 is easily exposed outside the insulating layer, and when the array substrate and the color film substrate are connected through the silver dispensing technology, silver paste overflowing the silver dispensing portion is easily short-circuited with the signal line, so that the short circuit of the signal line is poor. As shown in fig. 1, the silver paste portions 04 and the signal lines 03 are usually disposed at different positions. As shown in fig. 2, which is a cross-sectional view along the dashed line a-a of fig. 1. The array substrate comprises a substrate 05, a signal wire 03 arranged on the substrate 05, a first insulating layer 06 arranged on the substrate and covering the signal wire, a second insulating layer 07 arranged on one side, away from the substrate 05, of the first insulating layer 06, and a silver dispensing portion 04 arranged on one side, away from the substrate 05, of the second insulating layer 07. With the development of the display panel towards the narrow frame direction, the wiring area space of the array substrate is limited, and the silver dispensing part 04 is closer to the signal line. When the silver dispensing part 04 and the color film substrate 09 are connected through silver dispensing, the silver paste 08 overflowing the silver dispensing part is still easy to short-circuit the signal line, so that the short circuit of the signal line is poor.
Based on this, the present exemplary embodiment first provides an array substrate, as shown in fig. 3, which is a schematic structural diagram of an exemplary embodiment of the array substrate of the present disclosure. Fig. 4 is a cross-sectional view of fig. 3 taken along the dashed line a-a.
