Embodiments of the invention provide a display device including a first guide member extending in a first direction, a second guide member extending in the first direction and facing the first guide member in a second direction crossing the first direction, a display panel disposed between the first guide member and the second guide member, a support member which supports a portion of the display panel, a first driving unit which moves the support member, and a second driving unit connected to one end of the display panel to roll or unroll the display panel. In such embodiment, both sides of the support member are inserted into guide grooves defined in an inner side surface of the first guide member and an inner side surface of the second guide member, which faces the inner side surface of the first guide member, and the support member moves along the guide grooves.

Embodiments of the invention provide a display device including a display panel, a support member disposed under the display panel, a first driving unit coupled to a predetermined portion of the support member to move the support member, a second driving unit connected to one end of the display panel to roll or unroll the display panel, a window disposed on an unrolled portion of the display panel and spaced apart from a rolled portion of the display panel, and a third driving unit connected to one end of the window spaced apart from the display panel to roll a portion of the window, which is spaced apart from the display panel. In such embodiments, the support member supports an unrolled portion of the display panel, the second driving unit is disposed between the first driving unit and the third driving unit, and the first, second, and third driving units rotate in a same direction as each other.
