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 a top surface of the support film and inner sides of the support film defining the first groove are acute angles.
