Provided is a laser device including a light source generating a laser beam, a stage, and a lens assembly disposed between the light source and the stage and irradiating the laser beam to a substrate disposed on the stage. The laser device is capable of irradiating a uniform laser beam over an entire processing area to which the laser beam is irradiated. Thus, the laser device may irradiate a uniform laser beam to not only a center area, but also the edge area of the processing area.

Laser device including lens assembly

A method of manufacturing the display apparatus, the method including preparing a substrate in which an opening area and a non-display area around at least a portion of the opening area are defined, forming, on the substrate, an insulating layer having an opening corresponding to the opening area and defining an irradiated region including a first area and a second area on the non-display area, forming a conductive pattern on the irradiated region, covering the first area, and exposing the second area, forming an organic material layer on the insulating layer and the conductive pattern, forming an electrode layer on the organic material layer, and removing, by irradiating a laser beam to the irradiated region, the conductive pattern, the organic material layer on the irradiated region, and the electrode layer on the irradiated region.

A display device includes a substrate, a pixel circuit unit which is disposed on the substrate and having a first hole, a light blocking layer which is disposed on the pixel circuit unit and having a second hole corresponding to the first hole, a light emitting layer disposed on the pixel circuit unit, and a sealing unit on the light blocking layer. The substrate includes a first layer having a depression corresponding to the first hole, and a second layer which is disposed between the first layer and the pixel circuit unit and having a third hole between the depression and the second hole. The sealing unit includes a cover portion on the light blocking layer, and an extension portion extending from the cover portion. The depression has a width larger than a width of the third hole.
