Abstract: A touch sensor includes a sensing electrode that receives a touch input disposed on a sensing area of a substrate; and a plurality of sensing lines disposed on a non-sensing area of the substrate. Each of the plurality of sensing lines includes a first area and a second area, and first and second metal layers electrically coupled to the sensing electrode. The second metal layer is disposed on the first metal layer, and an insulating layer is interposed between the first and second metal layers. The sensing lines include first and second sensing lines. The first and second sensing lines include the first and second metal layers in the first area. The first sensing line includes the first metal layer without the second metal layer in the second area, and the second sensing line includes the second metal layer without the first metal layer in the second area.

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.

Abstract: A display device is disclosed. In one aspect, the display device includes a substrate including a display area and a non-display area adjacent to the display area and a display member formed over the substrate in the display area. The display device also includes an encapsulation layer formed over the display member and encapsulating the display member together with the substrate and a plurality of first touch lines formed over the encapsulation layer in the display area. The first touch lines extend in a first direction. The display device further includes a plurality of second touch lines formed on the same layer as the first touch lines in the display area. The second touch lines extend in the first direction and are spaced apart from the first touch lines.
