Abstract: A display device includes a display panel, a support film, and a polymer layer. The display panel includes a display area comprising a first area that is bendable, and a non-display area adjacent to the display area. The support film is coupled to a bottom surface of the display panel. The support film includes a first groove overlapping with the first area. The polymer layer is disposed in the first groove. The polymer layer includes a material with higher flexibility than the support film. Angles formed by the top surface of the support film and inner sides of the support film defining the first groove are acute angles.

Abstract: A display device comprises a substrate, a pixel electrode, a common electrode, an intermediate layer, a semiconductor layer, a metal layer, and an organic layer. The substrate includes an opening area, a peripheral area surrounding the opening area, and a display area surrounding the peripheral area. The pixel electrode overlaps the display area. The common electrode overlaps the pixel electrode. The intermediate layer is disposed between the pixel electrode and the common electrode and includes a light emitting layer and a functional layer. The semiconductor layer overlaps the peripheral area and is spaced from the display area. The metal layer overlaps the semiconductor layer. The organic layer is disposed between the semiconductor layer and the metal layer. The common electrode, the functional layer, and the metal layer respectively have a first opening, a second opening, a third opening overlapping each other and overlapping the semiconductor layer.
