A display panel may include an insulating substrate having a display region and a peripheral region adjacent to the display region; a plurality of insulating layers on the insulating substrate; a pixel on the display region, the pixel including a thin-film transistor and an organic light emitting device connected to the thin-film transistor; and a crack dam on the peripheral region and spaced apart from the pixel. The crack dam may be disposed adjacent to one of side surfaces of the insulating substrate extending in a first direction. The crack dam may include a plurality of insulating patterns, which are extended in the first direction and are spaced apart from each other in a second direction crossing the first direction, and a plurality of conductive patterns, which are disposed to fill gap regions between the insulating patterns.
