This allows a user to, conveniently use the display apparatus in order to enable quality of use to be improved during a tilting operation, and slim and elegant appearance to be implemented. The display apparatus includes a display configured to display an image on the front surface, a stand supporting the display, and a hinge device connecting the display to the stand such that the display may be tilted, wherein the hinge device includes a guide member formed on a rear surface of the display, a latch fixed to the stand and to slide along the guide member when the display is tilted, and a fixing member fixing the display not to move when an external force applied to the display is removed. ## Claims ### Claim 1 A display apparatus, comprising a display configured to display an image on a front surface thereof; a stand configured to support the display; and a hinge device configured to connect the display to the stand such that the display is tilted, wherein the hinge device includes a guide member formed on a rear surface of the display, a latch fixed to the stand and configured to slide along the guide member when the display is tilted, and a fixing member configured to fix the display such that the display is not moved when an external force applied to the display is removed. ### Claim 2 (depends on 1) The display apparatus according to claim 1, wherein the fixing member is a hydraulic hinge in which fluids are received in a cylinder. ### Claim 3 (depends on 2) The display apparatus according to claim 2, wherein the hydraulic hinge includes a piston received in the cylinder, and the piston reciprocates in the cylinder when a force greater than the hydraulic power of the hydraulic hinge is applied to the display. ### Claim 4 (depends on 2) The display apparatus according to claim 2, wherein the hydraulic hinge includes a side mounted on the rear surface of the display by an axis of rotation, and rotates with respect to the axis of rotation when the display is tilted. ### Claim 5 (depends on 3) The display apparatus according to claim 3, wherein the latch is connected to the stand by a fixing bracket. ### Claim 6 (depends on 5) The display apparatus according to claim 5, wherein the hydraulic hinge includes another side on which the latch is connected to the fixing bracket. ### Claim 7 (depends on 6) The display apparatus according to claim 6, wherein the hydraulic hinge is rotatably mounted on the fixing bracket along the axis of rotation. ### Claim 8 (depends on 1) The display apparatus according to claim 1, wherein the guide member includes a rail member that slides by inserting the latch into the guide member. ### Claim 9 (depends on 8) The display apparatus according to claim 8, wherein the display has a tilting angle limited by the length of the rail member. ### Claim 10 (depends on 3) The display apparatus according to claim 3, wherein the hydraulic hinge includes a side mounted on the display, and the other side mounted on the stand, so that the hydraulic hinge is reduced or extended by the external force applied to the display, and the display is tilted. ### Claim 11 (depends on 1) The display apparatus according to claim 1, wherein the fixing member is configured as a leaf spring including one end fixed to the rear surface of the display, and the other end formed at a free end. ### Claim 12 (depends on 11) The display apparatus according to claim 11, further comprising a pressure member configured to pressurize the leaf spring on the rear surface of the display. ### Claim 13 (depends on 12) The display apparatus according to claim 12, wherein the pressure member pressurizes the leaf spring when the display is tilted. ### Claim 14 (depends on 13) The display apparatus according to claim 13, wherein the pressure member applies a force to the leaf spring in an opposite direction to an elastic force applied by the leaf spring to the pressure member. ### Claim 15 (depends on 14) The display apparatus according to claim 14, wherein the pressure member includes an elastic member mounted thereon, and a direction of an elastic force of the elastic member is opposite to a direction of an elastic force of the leaf spring. ### Claim 16 (depends on 12) The display apparatus according to claim 12, wherein the pressure member includes a roller configured to pressurize the fixing member and move along the fixing member. ### Claim 17 A hinge device mounted on a stand such that a display is tilted, comprising: a fixing member mounted on a rear surface of the display, and configured to support the display such that the display is maintained in a tilted position at a predetermined angle; and a fixing bracket to connect the fixing part to the stand. ### Claim 18 (depends on 17) The hinge device according to claim 17, wherein the fixing member includes a hydraulic hinge in which fluids are filled in a cylinder, and the display is tilted only when an external force greater than the hydraulic power in the cylinder is applied. ### Claim 19 (depends on 18) The hinge device according to claim 18, wherein the hydraulic hinge includes one side mounted on the rear surface of the display, and the other side is connected to the stand, so that the hydraulic hinge is reduced or extended as the display is tilted. ### Claim 20 (depends on 17) The hinge device according to claim 17, wherein the stand includes a pressure member configured to pressurize the fixing member, and the fixing member is formed of a leaf spring with an elastic force acting in an opposite direction to the force applied to the fixing member by the pressure member. ### Claim 21 A display apparatus, comprising: a hinge device configured to connect a display to a stand such that the display is tilted, wherein the hinge device includes a guide member, a latch configured to slide along the guide member when an external force is provided to tilt the display, and a fixing member configured to fix the display such that the display is not moved when the external force applied to the display is removed. ### Claim 22 (depends on 21) The display apparatus of claim 21, further comprising a display configured to display an image on a front surface thereof. ### Claim 23 (depends on 22) The display apparatus of claim 22, further comprising a stand configured to support a display. ### Claim 24 (depends on 21) The display apparatus of claim 21, wherein the guide member is formed on a rear surface of the display apparatus. ### Claim 25 (depends on 21) The display apparatus of claim 21, wherein the latch is fixed to the stand. ### Claim 26 (depends on 24) the display apparatus of claim 24, wherein the guide member includes a rail member that slides by inserting the latch into the guide member.
