  • Publication number: 20230371312
    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.

  • Publication number: 20230055784
    Abstract: A display panel includes a substrate including a first area, a second area surrounding the first area, and a third area surrounding the second area, and a barrier part disposed on the substrate in the second area and including a first partition including a concave-convex structure on a surface facing the first area in a plan view. The display panel further includes a filling layer disposed on the substrate in the first area and the second area and adjacent to the concave-convex structure and a light emitting diode layer disposed in the third area on the substrate and adjacent to the first partition.
