A display device includes a display panel including a first non-folding region, a folding region, and a second non-folding region, a protective film below the display panel, and an adhesive layer between the display panel and the protective film, and a cutout portion, passing through an entirety of the protective film in a thickness direction and at least a portion of the adhesive layer in the thickness direction, is defined.

Display device

Provided is an electronic device including a display panel including a base substrate, pixels, a first insulation layer, and panel pads spaced along a first direction from pixels and each arranged along a second direction crossing the first direction, a circuit board disposed on the display panel and connected to panel pads, and an adhesive interconnect layer disposed between the display panel and the circuit board and electrically connecting the display panel and the circuit board. The circuit board includes a flexible substrate including a top surface facing the base substrate, output pads disposed on the flexible substrate and connected to panel pads, each obliquely extending in the first and second directions and arranged along the second direction, an alignment pad spaced along the second direction from output pads, and a stress relaxation pad disposed between output pads and alignment pads and electrically insulated from panel pads.
