Abstract: A display device includes a housing, a display module, a support film, and a frame. The display module is accommodated in the housing in a first state and unrolled from the housing to a first direction in a second state. The support film is accommodated in the housing in the first state and unrolled from the housing to the first direction in the second state to support the display module. The frame shrinks to a first shape in the first state and expands to a second shape in the second state in a way such that the frame applies a tensile stress to the support film in the second state.
