摘要： A foldable display apparatus includes a display panel that is foldable, a protective film, that is foldable, disposed on one surface of the display panel, and a sub-layer disposed on the protective film. A folding portion of the display apparatus includes a thin film zone, of the protective film, that is thinner than a main body of the protective film, and a pair of bumps disposed on opposing sides of the thin film zone, each of the pair of bumps having a thickness greater than that of the main body of the protective film. When the foldable display apparatus is in a folding state, a portion of the sub-layer is provided between the pair of bumps and is pressed by the pair of bumps.

摘要： A display device includes a display panel that is bent with respect to a bending area. A coating layer is disposed below the display panel and may include a resin. A portion of the coating layer, which is adjacent to the bending area, may have a thickness that gradually decreases in a direction toward the bending area.

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.
