Patent ID: 8767161

Claim:
A display device comprising: a display region where display pixels are arranged in a matrix on a substrate; a terminal section that is disposed at a side portion of the substrate; and signal lines that are disposed via a region between the display region and a side edge portion of the substrate and electrically connect the display pixels to the terminal section, wherein the signal lines include a first signal line formed close to the side edge of the substrate, a second signal line formed on the first signal line via a first insulating film, and a transparent conductive film formed on the second signal line via a second insulating layer and electrically connecting the first signal line to the second signal line, wherein the transparent conductive film is formed so as to cover a first connection hole which penetrates to the first signal line through the first insulating layer and the second insulating layer and a second connection hole which penetrates to the second signal line through the second insulating layer, wherein a recess portion is formed in the first insulating layer and/or the second insulating layer, and wherein the recess portion is disposed between the connection hole close to the side edge portion of the substrate of the first and second connection holes, and the side edge portion of the substrate, and at least a part of the side edge portion of the transparent conductive film extends to a bottom of the recess portion, wherein the display device further comprising: a barrier layer that is formed on the first insulating layer so as to overlap the recess portion, and wherein the first signal line and/or the second signal line intersect(s) the recess portion in a region where the barrier layer is formed.
