In addition, since the front lower portion is supported by the rollover part 18, it does not fall forward.

When the display device is packaged (or stored without being used), as shown in FIG. 6, the first and second support units 20 and 40 are unfolded in a straight state and then folded to closely contact the rear surface of the main body 10. . At this time, since the cam protrusion 34 of the cam unit 30 is located in the first locking groove 32a, the first support unit 20 is not refracted and is maintained in a straight state. In this case, since the connecting member 50 is restrained by the first and second restraining devices 61 and 62, the first and second supporting units 20 and 40 are removed from the back of the main body 10 unless they are separated by an external force. Do not deviate.

When the display device is to be used on a wall, the hook part 51 provided on the connecting member 50 is rotated upward to extend as shown in FIG. 7. And as shown in FIG. 8, the hook part 51 is fastened to the protrusion part 100 of a wall surface. This allows the display device to be used on the wall.

Meanwhile, when the first and second support units 20 and 40 are folded toward the rear surface of the main body 10 as shown in FIG. 6, when the first and second support units 20 and 40 are folded as shown in FIG. 2, as shown in FIG. ) In the direction of arrow A (forward). In this case, since the hook part 51 rotates while being supported on the upper rear side of the main body 10, the connecting member 50 is easily separated from the first and second restraining devices 61 and 62. That is, since the hook portion 51 rotates around the point B like the lever, the connecting member 50 is easily separated.

As described in detail above, the display device according to the present invention can be folded in such a manner that the first and second support units are straightly folded and then closely adhered to the back of the main body, thereby simplifying the configuration of the support device than before. There is an effect that can minimize the volume in the state.

In addition, the present invention can be installed in the upright state on the table by using the first and second support units as well as the effect of adjusting the screen angle of the main body.

In addition, the present invention has the effect that can be used to hang on the wall using the hook portion in a folded state in a manner of being in close contact with the back of the main body and the first support unit.
