Abstract: A method of manufacturing an organic light-emitting diode (OLED) display is disclosed. In one aspect, the method includes forming a color filter on a thin film transistor substrate, forming an organic planarization layer on the color filter, and performing a vacuum heat-treatment on the color filter and organic planarization layer. The method also includes forming a first electrode on the organic planarization layer, forming an organic light-emitting layer on the first electrode, and forming a second electrode on the organic light-emitting layer. The vacuum heat-treatment is performed at a temperature in the range of about 150° C. to about 300° C. under a pressure substantially equal to or lower than about 10−3 Torr before the organic light-emitting layer is formed.

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.
