A display device includes a housing; at least one roller positioned within the housing; a display portion including a display panel and a module cover; and at least one support connected to a top of the display portion and to raise or lower the display portion. The display panel and the module cover transition from a first state where the display panel and the module cover are wound around the at least one roller to a second state where the display panel and the module cover are unwound from the at least one roller, in contact with each other, and exposed out of the housing. The at least one support includes an upper link, one end portion of which is connected to the top portion of the display portion; a lower link, one end portion of which is positioned inside of the housing; and a hinge to connect the upper link and the lower link, the upper link and the lower link including first and second upper links and first and second lower links, respectively, which operate together with the hinge during the transition from the first state to the second state.
