摘要： An array structure and a method for manufacturing the same, an array substrate and a display device are provided, the array structure comprises signal input pads (3, 4) and a gate insulating layer (1), wherein the gate insulating layer (1) has grooves (P) in which the signal input pads (3, 4) are located. The grooves (P) function to accommodate the signal input pads (3, 4) for a test such as an array test and a cell test due to a position of the grooves (P) being lower than other layer structures. By means of the groove design, it is possible to decrease a difference of heights of the signal input pads and the display region, increase flatness of the display panel, further improve the uniformity of the aligning, improve the Mura defect caused by the aligning difference due to the height difference during the aligning process, and improve the product properties.
