A display device is provided, which includes a first substrate, a first display structure, a second display structure, a first optical film, a second optical film, a first adhesive layer and a second adhesive layer. The first and second display structures are disposed on the first substrate. The first display structure is disposed between the first substrate and the first optical film. The second display structure is disposed between the first substrate and the second optical film. The first and second optical films are separated. The first adhesive layer is disposed between the first display structure and first optical film. The second adhesive layer is disposed between the second display structure and second optical film. The first and second display structures are different from each other and are selected from a liquid-crystal display, an organic light-emitting diode display, an inorganic light-emitting diode display or a laser display.
