    Abstract: A display device includes a substrate including a display area and a non-display area outside the display area, a plurality of pixels located in the display area, a driving circuit driving the pixels, and a pad portion located in the non-display area and electrically connected to the driving circuit through a plurality of outer wirings. The pad portion includes a plurality of pad wirings each electrically connected to corresponding ones of the outer wirings. The pad wirings includes a first pad wiring and a second pad wiring separated from each other. The first pad wiring includes a first electrode layer, an insulating layer on the first electrode, and a second electrode layer on the insulating layer in a stacking direction, the second electrode layer being connected to the first electrode layer. The second pad wiring includes the first electrode layer but not the second electrode layer.

    IPC: H01L27/32

    Abstract: A display device includes a substrate, a pixel structure, a lighting circuit part, a driving integrated circuit part, a first lighting wire, a second lighting wire, and a connection electrode. The substrate includes a display area and a pad area. The pixel structure is on the substrate in the display area to emit light. The lighting circuit part is on the substrate in the pad area, and is electrically coupled to the pixel structure. The first lighting wire is spaced apart from a first side of the driving integrated circuit part in a first direction, and is coupled to the lighting circuit part. The second lighting wire is spaced apart from a second side facing the first side of the driving integrated circuit part in a second direction opposite to the first direction. The connection electrode electrically couples the first lighting wire and the second lighting wire to each other.
