摘要： A display device includes a display panel in which a display region and a pad region are defined. The display panel includes a base substrate, pixels disposed on the base substrate and disposed in the display region, a pad disposed on the base substrate, disposed in the pad region, and including a first surface and second surfaces connected to the first surface, and a protective layer which covers the pad and in which an opening exposing a first upper surface portion of the first surface of the pad is defined. A first thickness of a first portion of the protective layer covering a second upper surface portion of the first surface of the pad adjacent to the first upper surface portion of the first surface of the pad may be greater than a second thickness of a second portion of the protective layer covering second surfaces of the pad.

摘要： An OLED display device includes a substrate. A first electrode is disposed on the substrate (110). An organic light emitting layer (212) is disposed on the first electrode (211). A second electrode (213) is disposed on the organic light emitting layer. A thin film encapsulation layer (310) is disposed on the second electrode. The thin film encapsulation layer includes at least one inorganic layer (310, 330) and at least one organic layer (320) 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.
