  • Patent number: 11404667
    Abstract: A display device and a method of manufacturing the display device that is capable of easily bending the display device, simplifying manufacturing processes, and reducing manufacturing costs are provided. The display device includes a substrate including a bending area; a display element disposed on an upper surface of the substrate; and a protective layer disposed on a lower surface of the substrate. A portion of the protective layer that is disposed in the bending area has a material stiffness lower than a material stiffness of another portion of the protective layer.

  • Patent number: 10978669
    Abstract: A display device is provided. The display device includes: a substrate; a driving thin film transistor disposed over the substrate; a pixel electrode electrically connected to the driving thin film transistor; a pixel-defining layer including an opening overlapping the pixel electrode; an intermediate layer overlapping a portion of the pixel electrode exposed through the opening, the intermediate layer including an emission layer; an opposite electrode disposed on the intermediate layer; an organic control layer disposed on the opposite electrode, the organic control layer having hydrophilicity; an organic encapsulation layer disposed on the organic control layer; and at least one inorganic encapsulation layer overlapping the organic encapsulation layer.
