Display device and electronic device including the same

Abstract

A display device includes a base substrate having an active region and a peripheral region adjacent to the active region, a circuit element layer including a barrier layer on the base substrate, insulating layers on the barrier layer, and transistors each including conductive patterns between the insulating layers, a display element layer including light-emitting elements connected to the transistors, display pads in a peripheral region and connected to the transistors, a circuit board including board pads coupled to the display pads, and a film layer between the display pads and the board pads, wherein side surfaces of the insulating layers define a groove, the groove exposing a portion of the barrier layer and located between adjacent display pads of the display pads, and the film layer is in contact with the portion of the barrier payer exposed by the groove.
