Abstract: A display device may include a display panel including a signal pad and a circuit board including a connection pad having a first connection pad portion and a second connection pad portion. The second connection pad portion may be thicker than the first connection pad portion and may not be overlapped with the first connection pad portion in a plan view. The connection pad may be in contact with the signal pad. A first surface roughness between the first connection pad portion and the signal pad may be greater than a second surface roughness between the second connection pad portion and the signal pad.

Abstract: A display device includes: a display panel driven to display an image, the display panel including a substrate including a display area at which the image is displayed; a terminal pad on the substrate and through which a driving signal is applied to the display area; a driving chip through which the driving signal is applied to the terminal pad; and a non-conductive film which fixes the driving chip to the substrate. The driving chip includes: a non-conductive elastic support body projected from a surface of the driving chip; a bump wiring on the non-conductive elastic support body, the bump wiring directly contacting the terminal pad to apply the driving signal to the terminal pad; and a dispersed particle on the non-conductive elastic support body.
