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.
