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.
