Abstract: A material-removing heater device including: a first terminal portion defining a first electrode; a second terminal portion defining a second electrode; and a heating portion which connects the first terminal portion to the second terminal portion, the heating portion heatable by a flow of electrical current from the first terminal portion to the second terminal portion to remove a portion of material of a display device. The heating portion defines a lower end surface of the material-removing heater device at which the material-removing heater device contacts the material of the display device, the heating portion disposes the lower end surface to have a concave shape, and the heating portion which is heated deforms the lower end surface from the concave shape to have a planar shape.

Abstract: A display device includes a display panel including: a bending area at which the display panel is bent with reference to a bending axis, and a non-bending area at which the display panel is not bent and at which an image is displayed; and a support member on which is supported the display panel, defining: a recessed portion disposed in the bending area; first and second bumps spaced apart from each other to define the recessed portion therebetween; and extensions extended from the first and second bumps, in a direction away from the recessed portion, to opposing ends of the support member, respectively. In cross-section, a size of the first bump is different from a size of the second bump.

Abstract: An OLED device includes a display panel including a display region and a pad region located at a first side of the display region. The pad region includes a bending region located in a portion of the pad region adjacent to the display region and in a pad electrode region located in a remaining portion of the pad region. A lower protection film is on a lower surface of the display panel and exposes a portion of the bending region. The lower protection film includes a first lower protection film including a first concave-convex pattern in the bending region adjacent to the display region. A second lower protection film is spaced apart from the first lower protection film and includes a second concave-convex pattern in the bending region adjacent to the pad electrode region. The second concave-convex pattern has a shape that is insertable into the first concave-convex pattern.

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.
