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.
