Abstract: A display device includes a display panel and a circuit board. The display panel includes a display region and a bonding region. A plurality of pixels is disposed in the display region. The bonding region is spaced apart from the display region in a first direction. A plurality of pad electrodes is disposed in the bonding region. The circuit board is disposed on the display panel. The circuit board includes a first portion overlapping the display panel between the display region and the bonding region in a plan view. Accordingly, a dead space of the display device may be reduced, and a region in which a battery or the like is disposed in the display device may be secured by reducing an area in which the circuit board is disposed after the display panel is bent.

Abstract: A display device includes a display area and a non-display area including a first driving pad portion at which a display panel is connected to an integrated circuit chip by a solder bump having a width. The first driving pad portion includes a first pad through which an electrical signal transmits between the first driving pad portion and the integrated circuit chip, and a second pad by which alignment between the first driving pad portion and the integrated circuit chip is determined. The second pad of the first driving pad portion includes a (2-1)-th pad having a width which is the same as the width of the solder bump and a (2-2)-th pad having a width which is larger than the width of the (2-1)-th pad.
