Embodiment Construction
[0035] The structure and principle of the present invention will be described in detail below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, not to limit the protection scope of the present invention.
[0036] Such as figure 2 As shown, this embodiment provides an array substrate, including: the first metal connection part 2 and the second metal connection part 4 located in different layers, and also includes a The transparent conductive film layer 6 of part 4;
[0037] The first metal part 2 and the second metal connection part 4 are separated by the first insulating layer 3; the first metal connection part 2 and the second metal connection part 4 are arranged in a direction perpendicular to the plane of the array substrate overlap at least partially.
[0038] In this embodiment, the first metal connection part and the second metal connection part at least partially overlap in a direction perpendicular ...

The invention relates to an array substrate, a display device and a method for manufacturing the array substrate. The array substrate comprises a first metal connecting portion and a second metal connecting portion, wherein the first metal connecting portion and the second metal connecting portion are located in different layers. The array substrate further comprises a transparent conductive film layer used for connecting the first metal connecting portion and the second metal connecting portion. The first metal connecting portion is separated form the second metal connecting portion through a first insulating layer, and the first metal connecting portion and the second metal connecting portion are at least partly overlapped in the direction perpendicular to the plane where the array substrate is located. The array substrate, the display device and the method for manufacturing the array substrate have the advantages that the first metal connecting portion and the second metal connecting portion are at least partly overlapped in the direction perpendicular to the plane where the array substrate is located, the distance from the transparent conductive film layer used for connecting the first metal connecting portion and the second metal connecting portion to the array substrate in the parallel direction is greatly shortened, the size of the contact resistance when the transparent conductive film layer makes contact with the first metal connecting portion and the second metal connecting portion is reduced, and the generation of a transparent conductive film layer slope is avoided.
