Abstract: A display device includes an active region including pixels receiving data signals through data lines, and a non-active region on a side of the active region in a first direction and including a pad portion. The display device includes non-active fan-out wirings in the non-active region and connected to the pad portion, signal wirings extending in the first direction across the active region and connected to the pixels, and connection wirings passing through the active region and connecting some of the non-active fan-out wirings and some of the signal wirings. Each of the connection wirings includes first and second extension portions made of a first conductive layer, and a third extension portion made of a second conductive layer different from the first conductive layer. The first and second extension portions extend in the first direction, and the third extension portion extends in a second direction intersecting the first direction.
