Abstract: An organic light emitting display device includes a display panel including a display region where a plurality of pixels are disposed, a pad region including a bending region and a pad electrode region where pad electrodes are disposed, a polarizing layer disposed in the display region, and a lower protection film disposed on a lower surface of the display panel. The lower protection film includes a first and a second lower protection film pattern. The first lower protection film pattern is disposed in the display region, and the second lower protection film pattern in the pad electrode region such that a lower surface of the display panel in the bending region is exposed. The bending protection layer has an upper surface with a height that is less than a height of the polarizing layer, and is disposed in the bending region on the display panel.

Abstract: A display device includes a display panel and a signal transmission film including a first extension portion, a second extension portion, and a first dummy pattern. The signal transmission film is connected to one side of the display panel. The first extension portion extends in a first direction, and a first contact hole is formed at a first side of the first extension portion. The second extension portion extends from the first side of the first extension portion in a second direction which is different from the first direction. The first dummy pattern is disposed adjacent to the first contact hole at the first side.
