Abstract: A display device includes 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. 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.
