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 apparatus includes a substrate including a display area, a non-display area outside the display area, a pad area located in the non-display area, and a bending area between the display area and the pad area. The display apparatus includes a first voltage line having a first main voltage line disposed between the display area and the bending area, and a first connection portion protruding from the first main voltage line, extending toward the pad area, and crossing the bending area. The display apparatus includes a fan-out portion disposed between the display area and the pad area on the substrate and including conductive lines that connect the display area to the pad area, and a strain gauge disposed in the bending area. The strain gauge overlaps the first connection portion of the first voltage line in the bending area.
