Abstract: A method manufacturing a display device includes: forming a pixel circuit in a display area; forming a sacrificial layer on an insulating layer arranged in a non-display area, the sacrificial layer including an isolated pattern hole; forming functional layers and an opposite electrode of an organic light-emitting diode that extends over the display area and the non-display area, the functional layers and the opposite electrode covering the sacrificial layer; irradiating a laser beam to the opposite electrode through the sacrificial layer and the pattern hole from below a substrate; and lifting off the sacrificial layer from the insulating layer and simultaneously, lifting off the opposite electrode to which the laser beam is irradiated, wherein at least a portion of the functional layers is left on a portion of the insulating layer corresponding to the opposite electrode that is removed.

Abstract: A display apparatus comprises a first substrate comprising a first external surface and a first internal surface; a second substrate having a second external surface and a second internal surface facing the first internal surface of the first substrate; and a display unit disposed between the first and second substrates and comprising an array of pixels. The first substrate comprises a first side connecting the first external surface and the first internal surface. In a cross section perpendicular to the first external surface, the first side comprises a first straight region and a first curved region located between the straight region and the first internal surface. The second substrate comprises a second side connecting the first external surface and the first internal surface. The second side comprises a second straight region and a second curved region located between the straight region and the second internal surface.
