A display apparatus comprising: a display panel; a back frame configured to be attached to a wall structure (WALL) by a fixing element; a height adjustment element joined to the back frame, including a permanent magnet and a height of the height adjustment element being adjustable; and a position adjustment element fixed to a rear surface of the display panel, including a magnetic material mounted by a magnetic force of the height adjustment element, and adjusting a position to which the position adjustment element is attached to, on a plane defined by the height adjustment element; characterised in that the position adjustment element further includes: an attaching surface fixed to the display panel; a position adjusting surface protruding from the attaching surface toward the height adjustment element; a position limiting hole formed at the position adjusting surface; an adjusting chamber formed between the attaching surface and the position adjusting surface; the display apparatus further comprising a position limiter having: a head mounted in the adjusting chamber; an extrusion protruding from a center portion of a bottom surface of the head; and a cushion attached on an upper surface of the head, wherein the position limiting hole has a diameter smaller than that of the head and larger than that of the extrusion, and wherein the extrusion is configured to penetrate the position limiting hole and to be inserted into a base hole of the height adjustment element; wherein the height adjustment element includes: a screw portion joined to the back frame and configured to adjust the height; and a mount disposed on the screw portion and facing the position adjustment element; wherein the position adjusting surface is settled on a mount surface defined at an upper surface of the mount by the magnetic force of the height adjustment element, and configured to change the position of the position adjusting surface on a plane of the mount surface by an external force; wherein the position adjusting surface is configured to be freely movable within the area of the mount surface on a XY-plane formed by the mount surface, and wherein a disposed height of the display panel is controllable by the height adjustment element, and the height of the display panel is adjustable on a Z-axis. a display panel;
