    Abstract: An OLED display device includes a substrate. A first electrode is disposed on the substrate. An organic light emitting layer is disposed on the first electrode. A second electrode is disposed on the organic light emitting layer. A thin film encapsulation layer is disposed on the second electrode. The thin film encapsulation layer includes at least one inorganic layer and at least one organic layer that is disposed alternately with the at least one inorganic layer. The at least one organic layer includes a low refractive index layer overlapping the organic light emitting layer and a high refractive index layer disposed on the low refractive index layer. The high refractive index layer includes a convex surface protruding toward the organic light emitting 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.

    Abstract: A display device includes: a substrate; a display element on the substrate; a thin-film encapsulation layer on the display element, the thin-film encapsulation layer including at least one inorganic layer and at least one organic layer; and a lower layer below the thin-film encapsulation layer, the lower layer including a first surface parallel to an upper surface of the substrate and a second surface extending in a direction crossing the upper surface of the substrate. The at least one inorganic layer is has a first thickness on the first surface of the lower layer and a second thickness on the second surface of the lower layer, the first thickness is greater than or equal to the second thickness, and a ratio of the second thickness to the first thickness is about 0.51 or more.
