Abstract: A display device of the invention includes pixels each connected to at least one of scan lines and at least one of emission lines, a scan driver providing scan signals to the scan lines, and an emission driver including stages connected to the emission lines, each of the stages providing an emission signal to a corresponding emission line. A first stage among the stages includes a first transistor including a first electrode connected to a first power source line, a second electrode connected to a first emission line, and a gate electrode connected to a first scan line, and a second transistor including a first electrode connected to a first node and a second electrode connected to the first emission line.

Abstract: A display device includes a display panel, and a first flexible printed circuit board bonded to a side surface of the display panel. The display panel includes: a first substrate; a first extension wire on a top surface of the first substrate, the top surface being parallel to a first direction and a second direction, the second direction being perpendicular to the first direction; a first recess portion at a side surface of the first substrate; and a first pad that extends from the first extension wire in a third direction perpendicular to the first and second directions, the first pad being disposed in the recess portion, and the first extension wire and the first pad comprise the same material.
