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.
