Abstract

A matrix-type display capable of being repaired by pixel unit, Two or more of signal lines such as scanning lines, image signal lines and auxiliary signal lines and a pixel electrode are overlapped via an insulating layer, so that a defect such as the disconnection of the image signal lines and scanning lines, the short of the pixel electrode and the signal line, and the loss of electrode of a switching element, and a pixel defect can be repaired. Here, the layout of the auxiliary gate line and dual gate line can be modified.

Claims

1. A matrix-type display, comprising:

a first signal line and a second signal line electrically connected to each other;

a third signal line intersecting the first and the second signal lines and being insulated from the first and the second signal lines;

a switching element electrically connected to one of the first and the second signal lines and connected to the third signal line;

a first auxiliary member placed adjacent to the third signal line; and

a pixel electrode located substantially between the first and the second signal lines,

wherein at least one intersecting member intersects the third signal line at a first intersection and a second intersection and forms a first path between the first intersection and the second intersection, and the switching element is not disposed on the path, and

wherein said at least one intersecting member comprises at least one of;

(1) the second signal line; and

(2) the first auxiliary member.

2. The matrix-type display of claim 1, wherein the at least one intersecting member comprises the first auxiliary member and one selected from the group consisting of the second signal line and a second auxiliary member, and the first path includes a connection or an overlap between the first auxiliary member and the one selected from the group consisting of the second signal line and the second auxiliary member.

3. The matrix-type display of claim 1, wherein the first auxiliary member is connected to at least one of the first signal line and the second signal line.

4. The matrix-type display of claim 3, wherein the first auxiliary member is connected to the first and the second signal lines.

5. The matrix-type display of claim 1, wherein the first auxiliary member is disconnected from the first and the second signal lines.

6. The matrix-type display of claim 5, wherein the first auxiliary member includes the same layer as the first and the second signal lines.

7. The matrix-type display of claim 1, wherein the third signal line has a connect portion extending to the second intersection.

8. The matrix-type display of claim 1, wherein the first signal line intersects the third signal line at a third intersection and the first signal line and the at least one of the intersecting member form a second path between the first intersection and the third intersection.
