ARRAY SUBSTRATE AND MANUFACTURING METHOD THEREOF AND DISPLAY DEVICE

摘要

Disclosed are an array substrate (4) and a manufacturing method thereof and a display device. The array substrate (4) has such a structure that multiple signal lines (20) are arranged on the circumferential area of the array substrate (4), the part, used for being connected with an integrated circuit chip (1), of each signal line (20) is provided with at least two adhesive layers (6, 8) of different thicknesses, and the adhesive layers (6, 8) are electrically connected with each other through a conductive metal layer (11). A full-piece adhesive layer in the prior art is changed into the at least two adhesive layers, namely the two adhesive layers (6, 8) of the different thicknesses are arranged at a bonding position and connected with each other through the conductive metal layer (11), so that abnormal bonding caused by film thickness difference and metal layer deviation can be avoided, the occurrence of poor wiring caused by the abnormal bonding can be reduced, and the product quality can be improved. In the display device, the adhesive layers (6, 8) on the array substrate (4) are connected with a drive integrated circuit chip (1) in the display device through an anisotropic conductive film (2).
