Abstract
A display device comprises a circuit element layer on a substrate and comprising a thin film transistor, a storage capacitor, and a pixel electrode connected thereto, a display layer comprising an emission layer, an opposite electrode on the emission layer, and a functional layer, a thin encapsulation layer on the display layer, the thin encapsulation layer comprising at least one inorganic layer and at least one organic layer, and a through portion passing through the substrate, the circuit element layer, the display layer, and the thin encapsulation layer, wherein a slope angle of a lateral surface of the display layer adjacent to the through portion is different from that of one of a lateral surface of the substrate, a lateral surface of the circuit element layer, and a lateral surface of the thin encapsulation layer that are adjacent to the through portion.
