  • Organic light emitting display device
    Patent number: 11552153
    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.

  • Display apparatus and method of manufacturing the same
    Patent number: 11036071
    Abstract: A method of manufacturing a display apparatus is provided as follows. A substrate having a display portion on an upper surface of the substrate is prepared. A protection film having an opening is attached to a lower surface of the substrate so that the protection film overlaps the display portion. A support film is attached to the lower surface so that the support film is disposed within the opening of the protection film. A driving circuit chip is attached to the upper surface so that the driving chip is spaced apart from the display portion and the opening. At least a part of the support film is removed. The substrate is bent along a longitudinal direction of the opening.
