A system comprising a display device and stand for the display device, the stand comprising: a sliding portion extending toward a rear surface of the display device and supported at one end thereof on the display device; a supporting portion for slidably supporting the sliding portion; and a base for supporting the supporting portion, the base extending the supporting portion upward, wherein the supporting portion comprises: a slide panel to which a lower end of the sliding portion is coupled; a guide panel along which the slide panel is guided and moves in an extending direction of the supporting portion; and a spring capable for expanding and contracting while contacting the slide panel, and having at least one end thereof fixed to the guide panel, and providing drag preventing the slide panel from descending, so that the deadweight of the display device can be conveniently raised in an upward direction, and the sliding portion and the supporting portion are formed to extend in mutually different directions, characterized in that the sliding portion comprises a quadric crank mechanism for maintaining a tilt angle of the display device when a force below a predetermined level is applied to the display device, said quadric crank mechanism comprising: a link hinge providing a hinge connection between the sliding portion and the display device; a supporting hinge providing a hinge connection between the sliding portion and the supporting portion; a pair of auxiliary links (18,19) eccentrically connecting the link hinge to the supporting hinge; and a main link connecting the link hinge and the supporting hinge, wherein a first supporting axis is inserted so that is cannot rotate with respect to the supporting hinge, wherein a first friction portion and a second friction portion are fixed with respect to the first supporting axis, and at least one side thereof contacts the lower surface of the main link, and provides force pressing the main link in an upward direction when the main link rotates downward, wherein the first friction portion and the second friction portion are able to provide sufficient restoring force in any direction, when the display device moves upward or downward due to the wound directions being different with respect to the first supporting axis. a sliding portion extending toward a rear surface of the display device and supported at one end thereof on the display device; a supporting portion for slidably supporting the sliding portion; and a base for supporting the supporting portion, the base extending the supporting portion upward, a slide panel to which a lower end of the sliding portion is coupled; a guide panel along which the slide panel is guided and moves in an extending direction of the supporting portion; and a spring capable for expanding and contracting while contacting the slide panel, and having at least one end thereof fixed to the guide panel, and providing drag preventing the slide panel from descending, so that the deadweight of the display device can be conveniently raised in an upward direction, and the sliding portion and the supporting portion are formed to extend in mutually different directions, characterized in that the sliding portion comprises a quadric crank mechanism for maintaining a tilt angle of the display device when a force below a predetermined level is applied to the display device, said quadric crank mechanism comprising: a link hinge providing a hinge connection between the sliding portion and the display device; a supporting hinge providing a hinge connection between the sliding portion and the supporting portion; a pair of auxiliary links (18,19) eccentrically connecting the link hinge to the supporting hinge; and a main link connecting the link hinge and the supporting hinge, a link hinge providing a hinge connection between the sliding portion and the display device; a supporting hinge providing a hinge connection between the sliding portion and the supporting portion; a pair of auxiliary links (18,19) eccentrically connecting the link hinge to the supporting hinge; and a main link connecting the link hinge and the supporting hinge, wherein a first supporting axis is inserted so that is cannot rotate with respect to the supporting hinge, wherein a first friction portion and a second friction portion are fixed with respect to the first supporting axis, and at least one side thereof contacts the lower surface of the main link, and provides force pressing the main link in an upward direction when the main link rotates downward, wherein the first friction portion and the second friction portion are able to provide sufficient restoring force in any direction, when the display device moves upward or downward due to the wound directions being different with respect to the first supporting axis.
