Display device with driving IC having output pads with different heights

A display device comprising:

• a substrate including a display area and a pad area;
• a display structure disposed in the display area on the substrate;
• 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 disposed between the substrate and the upper output bumps, and having a first height;
• and
• second output pads disposed between the substrate and the lower output bumps, and having a second height that is smaller than the first height, wherein
• the driving integrated circuit further includes input bumps disposed in the input area on the bottom surface of the circuit part.
