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.
