Display device

A display device comprising:

• a display substrate including a display area on which a plurality of pixels are disposed and a pad area adjacent to an one side of the display area;
• a cover panel disposed under the display substrate;
• a first circuit board electrically connected to the pad area;
• a second circuit board electrically connected to the first circuit board and disposed under the cover panel;
• a control chip mounted on a first surface of the second circuit board;
• an adhesive layer attaching the second circuit board to the cover panel and, when viewed in a plan view, defining a first opening exposing a portion of the second circuit board at which the control chip is disposed;
• and
• a cover tape covering each of the first circuit board, the second circuit board, and the control chip.

• a cover panel disposed under the display substrate;
• a first circuit board electrically connected to the pad area;
• a second circuit board electrically connected to the first circuit board and disposed under the cover panel,
• wherein the first circuit board includes:
• a first part overlapping a part of the pad area,
• a second part having a curved shape extending around the cover panel and a first end connected to the first part, and
• a third part disposed under the cover panel and connected to a second end, opposite to the first end, of the second part;
• a control chip mounted on a first surface of the second circuit board;
• an adhesive layer attaching the second circuit board to the cover panel and, when viewed in a plan view, defining a first opening exposing a portion of the second circuit board at which the control chip is disposed;
• and
• a cover tape covering the first circuit board, a portion of the second circuit board between the third part of the first circuit board and the control chip, and the control chip, wherein the cover tape and the cover panel are arranged such that a side surface of the adhesive layer and a side surface of the second circuit board are exposed to the external of the display device.
