Abstract:
A method of manufacturing a display panel having an opening, a display area surrounding the opening, and a non-display area between the opening and the display area, the method includes the steps of: forming a pixel circuit including a at least one thin-film transistor in the display area, forming a first electrode electrically connected to the at least one thin-film transistor, forming a first layer having a plurality of slits in the non-display area, forming, on the first electrode, an intermediate layer and a second electrode that form a light-emitting element, the intermediate layer and the second electrode being disposed on the display area and the non-display area, and covering the first layer, lifting the second electrode off from the intermediate layer by irradiating a first laser beam having a first energy density toward the first layer, the intermediate layer, and the second electrode, which are stacked, and lifting off the first layer and the intermediate layer by irradiating a second laser beam having a second energy density greater than the first density toward the first layer.
