    Abstract: A display apparatus includes a substrate. A display element is disposed on the substrate. A first organic layer is disposed on the display element and includes a plurality of first organic patterns. The plurality of first organic patterns extends in a first direction and has reverse-graded sidewalls. A plurality of first light-shielding walls is disposed on sidewalls of the plurality of first organic patterns. A second organic layer is disposed on the first organic layer and includes a plurality of second organic patterns. The plurality of second organic patterns extends in the first direction and has sidewalls with alternating directions of inclination. A plurality of second light-shielding walls is disposed at sidewalls of the plurality of second organic patterns.

    Abstract: A pixel includes an organic light-emitting diode, a driving transistor, a first dual gate transistor, a first capacitor, and a compensation transistor. The organic light-emitting diode includes first and second terminals. The driving transistor generates the driving current and includes a first terminal to which a first power supply voltage is applied, a second terminal connected to the first terminal of the organic light-emitting diode, and a gate terminal. The first dual gate transistor is connected between the gate terminal of the driving transistor and the second terminal of the driving transistor and includes first and second sub-transistors. The first capacitor includes a first electrode to which the first power supply voltage is applied, and a second electrode connected to a first node that connects the first and second sub-transistors to each other. The compensation transistor includes a terminal connected between the second electrode and the first node.

    Abstract: A display panel including a glass substrate having an opening area, and a display area at least partially surrounding the opening area; a thin film transistor on the display area including a semiconductor layer and a gate electrode; a display element electrically connected to the thin film transistor; a multi-layer including an insulating layer and a lower insulating layer. The insulating layer is between the glass substrate and the display element and the lower insulating layer is between the glass substrate and the insulating layer; and a thin-film encapsulation layer covering the display element including an inorganic encapsulation layer and an organic encapsulation layer. The multi-layer includes a first groove between the opening area and the display area. A first width of a portion of the first groove in the lower insulating layer is greater than a second width of a portion of the first groove in the insulating layer.

    Abstract: A surface inspection apparatus and method, and a method of manufacturing a display device are disclosed. In one aspect, the surface inspection method includes placing an object on a stage comprising a top surface inclined at a predetermined angle with respect to a plane having a first direction and a second direction crossing the first direction. The method also includes irradiating light onto the object via a surface inspection unit. The method also includes obtaining a first image comprising first interference fringes captured by the imaging device, moving at least one of the surface inspection unit and the stage in at least one of the first and second directions, obtaining a second image including second interference fringes captured by the imaging device, and moving the surface inspection unit in the third direction so as to correct movement of the second interference fringes with respect to the first interference fringes.
