摘要： 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.

摘要： A display device and method of manufacture may include a display panel having a first region, a second region spaced apart from the first region, and a bending region between the first region and the second region. The bending region is bent along a bending axis. A functional layer is arranged between the first region and the second region of the display panel, a core is arranged in a bending space defined by the bending region of the display panel and a side surface of the functional layer. A filler is arranged in the bending space to surround the core. A protective film may be arranged between the display panel and the functional layer. A thickness of the protective film corresponding to the bending region may be less than a thickness of a portion of the protective film corresponding to the first region or the second region.

摘要： 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.

摘要： 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.
