Abstract
A display device includes a display panel and a driving circuit chip. The driving circuit chip includes a signal bump and an alignment bump. The display panel includes a pixel disposed in a display area, a signal pad disposed in a non-display area and corresponding to the signal bump, an alignment pad disposed in the non-display area and corresponding to the alignment bump, a reference pad that is disposed in the non-display area, is spaced apart from the alignment pad, and does not overlap the driving circuit chip in a plan view, and a signal line disposed in the display area and the non-display area and electrically connecting the pixel and the signal pad.

A display device comprising:
- a display panel comprising a display area through which an image is displayed and a non-display area defined adjacent to the display area;
- a driving circuit chip disposed in the non-display area and electrically connected to the display panel, and
- a flexible circuit board disposed in the non-display area and electrically connected to the display panel,
- wherein the driving circuit chip comprises:
- a signal bump;
- and
- an alignment bump, and
- the display panel comprises:
- a pixel disposed in the display area;
- a first signal pad disposed in the non-display area and corresponding to the signal bump;
- a second signal pad disposed in the non-display area and corresponding to the flexible circuit board;
- an alignment pad disposed in the non-display area and corresponding to the alignment bump;
- a reference pad that is disposed in the non-display area and does not overlap the driving circuit chip or the flexible circuit board in a plan view;
- and
- a signal line disposed in the display area and the non-display area and electrically connecting the pixel and the signal pad,
