Abstract

Disclosed are an array substrate and a display device which belong to the technical field of displays, and are intended to solve the technical problem of large width of the bezel of a liquid crystal display device. The array substrate is provided thereon with a fan-out zone which includes a plurality of conducting lines. At least one of the conducting lines includes a first metal wire and a second metal wire which are serially connected to each other. The second metal wire has a unit resistivity larger than that of the first metal wire. The conducting lines have different lengths, and the second metal wire in a shorter conducting line is longer than the second metal wire in a longer conducting line.

First claim

1 . An array substrate, which is provided thereon with a fan-out zone,
wherein the fan-out zone comprises a plurality of conducting lines, at least one of the conducting lines comprising a first metal wire and a second metal wire which are in series connection, the second metal wire having a unit resistivity larger than that of the first metal wire, and the conducting lines have different lengths, the second metal wire in a shorter conducting line being longer than the second metal wire in a longer conducting line.

2 . The array substrate according to claim 1 , wherein the array substrate comprises a first metal layer, a second metal layer, and a third metal layer.

3 . The array substrate according to claim 2 , wherein the second metal wire is located on the third metal layer.

4 . The array substrate according to claim 3 , wherein the first metal wire is located on the first metal layer or the second metal layer.

5 . The array substrate according to claim 4 , wherein the third metal layer has a thickness smaller than that of the first metal layer and smaller than that of the second metal layer.

6 . The array substrate according to claim 4 , wherein the second metal wire has a width smaller than that of the first metal wire.

7 . The array substrate according to claim 1 , wherein the first metal wire and the second metal wire are connected to each other by a transparent electrode.

8 . The array substrate according to claim 2 , wherein some of the conducting lines in the fan-out zone comprise only the first metal wire which comprises a single-layer metal segment and a double-layer metal segment which are in series connection, and
wherein the single-layer metal segment is located on the first metal layer or the second metal layer, and the double-layer metal segment is formed by two metal layers connected in parallel and located on the first metal layer and the second metal layer respectively.

9 . The array substrate according to claim 8 , wherein the closer a conducting line is to the right or left side of the fan-out zone, the longer the double-layer metal segment in the first metal wire is.

10 . A display device, comprising a color filter substrate and an array substrate,
wherein the array substrate is provided thereon with a fan-out zone, the fan-out zone comprises a plurality of conducting lines, at least one of the conducting lines comprising a first metal wire and a second metal wire which are in series connection, the second metal wire having a unit resistivity larger than that of the first metal wire, and the conducting lines have different lengths, the second metal wire in a shorter conducting line being longer than the second metal wire in a longer conducting line.

11 . The display device according to claim 10 , wherein the array substrate comprises a first metal layer, a second metal layer, and a third metal layer.

12 . The display device according to claim 11 , wherein the second metal wire is located on the third metal layer.

13 . The display device according to claim 12 , wherein the first metal wire is located on the first metal layer or the second metal layer.

14 . The display device according to claim 13 , wherein the third metal layer has a thickness smaller than that of the first metal layer and smaller than that of the second metal layer.

15 . The display device according to claim 13 , wherein the second metal wire has a width smaller than that of the first metal wire.

16 . The display device according to claim 10 , wherein the first metal wire and the second metal wire are connected to each other by a transparent electrode.

17 . The display device according to claim 11 , wherein some of the conducting lines in the fan-out zone comprise only the first metal wire which comprises a single-layer metal segment and a double-layer metal segment which are in series connection, and
wherein the single-layer metal segment is located on the first metal layer or the second metal layer, and the double-layer metal segment is formed by two metal layers connected in parallel and located on the first metal layer and the second metal layer respectively.

18 . The display device according to claim 17 , wherein the closer a conducting line is to the right or left side of the fan-out zone, the longer the double-layer metal segment in the first metal wire is.
