Screw holes 15 are provided in 13a, and four legs 13 that can be fixed by being pulled out from the back side 11c of the display body 11 by a predetermined length, respectively.

  FIG. 5 is a side perspective view showing a state where the display in the state of FIG. 3 is placed on a desk. As shown in FIG. 5, the display device 91 is in a state where the two legs 13 on the lower side of the display screen 11a are contracted and the two legs 13 on the upper side of the display screen 11a are pulled out and fixed by a predetermined length. By placing on the desk 81, the display screen 11a can be easily seen from the front side of the desk 81. If the tip 13a of the leg 13 is formed of a rubber material or coated with a rubber material, the frictional force of the tip 13a is increased when the display 91 is placed on the desk 81, and the display 91 stabilizes on the desk 81.

  FIG. 6 is a side view showing a state in which the legs of the first embodiment are all pulled out from the display and the tips of the legs are screwed to a thin plate. As shown in FIG. 6, the indicator 91 pulls out the four legs 13 uniformly, and screws the set screw 17 into the screw hole 15 of the leg 13 through the screw hole 82 a provided in the thin plate (wall plate) 82. Thus, it can be attached to a thin plate (wall plate) 82. This mounting method is used when the display 91 is mounted at the same height as the user's eyes.

  FIG. 7 is a side view showing a state in which the legs of Embodiment 1 are pulled out from the display to different lengths and the tips of the legs are screwed to a thin plate. As shown in FIG. 7, the display device 91 is in a state where the two legs 13 on the lower side of the display screen 11a are contracted and the two legs 13 on the upper side of the display screen 11a are pulled out and fixed by a predetermined length. The set screw 17 can be attached to the thin plate 82 by screwing the set screw 17 into the screw hole 15 of the leg 13 through the screw hole 82 a provided in the thin plate 82. This mounting method is used when the display 91 is mounted at a position higher than the height of the user's eyes.
