A display device comprising: a display panel to display an image; a chassis arranged on a back side of the display panel; a cover formed with an opening, the cover covering a back side of the chassis and a bottom side of the chassis; a stand to support the display device and being storable in an open space between the chassis and the cover; a locking device (160, 260, 360) to lock the stand in the open space to thereby store the stand within the display device and to release the stand from the open space; and a rotation guide, wherein the stand, the locking device, and the rotation guide are configured so that, when the stand is locked in the open space by the locking device and is thereby stored within the display device, the release of the stand from the open space by the locking device allows the stand to be pulled out of the display device through the opening by self-weight of the stand, and at least a portion of the stand to be rotated by the rotation guide, so that the stand is in position to support the display device, wherein the stand comprises: a body portion; a locked portion arranged at the top of the body portion and locked in the locking device; and a supporting portion arranged beneath the body portion and pulled out of the display device to support the display device when the stand is unlocked; wherein the supporting portion comprises a first supporter, a second supporter, and a rotation shaft, and the first supporter and the second supporter are provided to contact each other when the stand is stored in the display device, and to be unfolded by being rotated around the rotation shaft when the stand is pulled out of the display device, characterized in that the display device further comprises: a stand compartment comprising a gas cylinder provided to contract or expand by being engaged with vertical movement of the body portion, and the gas cylinder is provided to apply pressure to the body portion to rotate the first supporter and the second supporter. a display panel to display an image;
