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.
Claims19
A display device, comprising:
- a display panel including a signal pad;
- and
- a circuit board comprising a connection pad including a first connection pad portion and a second connection pad portion,
- wherein the connection pad is in contact with the signal pad;
- and
- wherein a first surface roughness between the first connection pad portion and the signal pad is different from a second surface roughness between the second connection pad portion and the signal pad.
A display device, comprising:
- a display panel including a signal pad;
- and
- a circuit board comprising a conductive pattern including a pad portion, which is in contact with the signal pad, and a line portion, which is not overlapped with the signal pad and is connected to the pad portion,
- wherein, a recessed space is defined on an upper surface of the pad portion facing the signal pad.
