A kind of array substrate and display device

Abstract

The present invention provides an array substrate and a display device. The array substrate includes a base substrate. At least three layers of mutually insulated signal lines are arranged in the non-display area of ​​the base substrate. The signal lines include a first layer extending in the same direction. The signal line and the second-layer signal line, and the third-layer signal line cross-isolated with the first-layer signal line and the second-layer signal line, and the distance between the third-layer signal line and the substrate substrate is greater than that of the first-layer signal line. The distance between the line and the signal line of the second layer and the base substrate, the orthographic projection of the signal line of the first layer on the base substrate and the orthographic projection of the signal line of the third layer on the base substrate have a first overlapping area, the second The orthographic projection of the signal line of the second layer on the base substrate and the orthographic projection of the signal line of the third layer on the substrate have a second overlapping area, and the first overlapping area and the second overlapping area are at least partially non-overlapping, thereby solving the difference in level difference Large third-layer signal lines are prone to breakage problems.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate and a display device. Background technique [0002] TFT-LCD (Thin Film Transistor-Liquid Crystal Display, Thin Film Transistor-Liquid Crystal Display) products are continuously improved and updated, making the wiring on the TFT-LCD array substrate more dense, especially the wiring in the fanout (fan-out) area of ​​​​the non-display area is particularly dense, please refer to figure 1 and figure 2 , figure 1 is a bottom view of the fanout area of ​​an array substrate in the prior art, figure 2 for figure 1 A cross-sectional view of the array substrate in the A-A direction, the non-display area of ​​the array substrate is provided with: a base substrate 101, a gate metal line 102, a gate insulating layer 103, a data signal line 104, a passivation layer (PVX) 105 and a touch panel Signal trace 106, from figure 2 It can be seen from the figure tha...
