    Abstract: A display device includes: a substrate including a first region, a second region, and a bending region, the bending region connecting the first region and the second region to each other; a display unit disposed on a first surface of the substrate in the first region thereof; in the first region of the substrate, a first passivation layer disposed on a second surface of the substrate which is opposite to the first surface of the substrate; and in the second region of the substrate, a second passivation layer disposed on the second surface of the substrate. Each of the first passivation layer and the second passivation layer includes a photocurable resin which is cured.

    Abstract: A display device includes a flexible substrate including a bending area corresponding to an area at which the display device is bent, and a first area and a second area which is spaced apart from the first area by the bending area, a display element unit disposed in the first area of the flexible substrate; and a buffer member disposed in the bending area of the flexible substrate. The buffer member in the bending area includes: a first buffer member having a first maximum thickness, and a second buffer member having a second maximum thickness which is smaller than the first maximum thickness. Among the first buffer member and the second member, the first buffer member disposed closer to the first area and the second member disposed closer to the second area.

    Abstract: A display device includes: a substrate including a first flat area, a second flat area, and a bending area between the first flat area and the second flat area; a display unit overlapping the first flat area and disposed on a surface of the substrate; first and second protection layers on an opposing surface of the substrate and overlapping the first and second flat areas, respectively. The first and second protection layers include a hardening member including a photo-hardening resin, the first protection layer includes a first inclination part at an end, the second protection layer includes a second inclination part at an end, the first inclination part has a first inclination angle with the opposing surface, the second inclination part has a second inclination angle with the opposing surface, and the first and second inclination angles are in a range of about 10 degrees to about 90 degrees.

    Abstract: A display device includes a bending area at which the display device is bendable; an organic light emitting element disposed on the substrate; an encapsulation layer covering an upper surface and a side surface of the organic light emitting element; and a bending area protection layer covering the bending area of the substrate. The upper surface of the encapsulation layer includes a nano structure defined by nano sized protrusions and depressions of the upper surface, and along the substrate, and the bending area is disposed separated from the encapsulation layer.

    Abstract: A display device includes a substrate which includes a pixel region and a peripheral region which is provided on at least one side of the pixel region, a plurality of pixels provided in the pixel region, a passivation layer that disposed on the substrate, a light emitting element disposed on the passivation layer and which emits light, and a sealing member which covers the light emitting element. The sealing member includes a first inorganic layer disposed on the light emitting element, a lens portion disposed on the first inorganic layer and which extracts light which is emitted from the light emitting element, an organic layer disposed on the lens portion, and a second inorganic layer disposed on the organic layer.
