A display device for a vehicle includes a first frame configured to be coupled to a dashboard of the vehicle, a second frame configured to move vertically relative to the first frame, and a flexible display having a first area that extends along the second frame and defines a flat surface and a second area that is configured to extend from the first area, where the display device is configured to vary a shape of the second area. The display device further includes a first roller that extends in an upward-downward direction and that supports an inner surface of the flexible display to allow the second area to be curved around the first roller, a first moving body is coupled to the second area, and a second actuator configured to move the first roller and the first moving body laterally relative to the second frame.
