Abstract
A display device includes a substrate including a display area and a pad area, a display structure disposed in the display area on the substrate, and a driving integrated circuit disposed in the pad area on the substrate and including a circuit part including an input area, a first output area adjacent to the display area, and a second output area between the input area and the first output area, upper output bumps disposed in the first output area on a bottom surface of the circuit part, and lower output bumps disposed in the second output area on the bottom surface of the circuit part. First output pads are disposed between the substrate and the upper output bumps, and have a first height. Second output pads are disposed between the substrate and the lower output bumps, and have a second height smaller than the first height.
