Patent ID: 8045084

Claim:
A display device comprising: a signal line formed on a substrate comprising an image display part which displays an image and a non-image display part adjacent to the image display part; a repair line formed on the substrate crossing and insulated from the signal line, the repair line having a width in an area where the repair line crosses the signal line narrower than a width in an area where the repair line does not cross the signal line; and a first redundancy conductive pattern formed on a first region of the substrate and insulated from the signal line and the repair line, the first redundancy conductive pattern disposed on a different layer from the repair line while interposing an insulating layer between the first redundancy conductive pattern and the repair line, wherein the first redundancy conductive pattern comprises a metal material, a portion of the first redundancy conductive pattern is overlapped with at least one of the signal line and the repair line and when the signal line is repaired, the repair line is connected with the signal line in the non-image display part, and wherein the first redundancy conductive pattern is formed where the signal line crosses the repair line.
