Abstract: A display device includes a base substrate layer including a first base substrate and a second base substrate separated from the first base substrate in a first direction, a flexible film disposed on a first surface of the base substrate layer, and one or more light emitting elements disposed on a first surface of the flexible film. The flexible film includes a flat portion and a bent portion. The bent portion is inserted into a space between the first base substrate and the second base substrate.
