The angle HRA1 of the first upper arm 73Ca from the ground and the angle HRA2 of the first lower arm 73Cb from the bottom can be the same, since the first upper arm 73Ca and the first lower arm 73Cb interlocked with each other. Further, the angles between the first upper arms 73Ca and the first lower arms 73Cb be equal on both sides, since the first upper arm 73Ca and the first lower arm 73Cb on each side are interlinked. Accordingly, the upper bar 75 raise or fall while being held horizontally without leaning to one side. That is, the angles between the first upper arms 73Ca and the first lower arms 73Cb on both sides can be independent of the height of the upper bar 75 to be equal from the ground.

In the second upper and lower arms 73Fa and 73Fb possibly no gear is formed. The angle between the second upper arm 73Fa and the second lower arm 73Fb is equal to that between the first upper arm 73Ca and the first lower arm 73Cb ,

As in 17E In a display device according to an embodiment, the upper arm may be shown 73a and the lower arm 73b be formed from a single arm. Accordingly, when an external force F is exerted on one side, the angle HLA may be between the upper arm 73a and the lower arm 73b be changed. In this case, the scoreboard may tilt to one side.

In contrast, as in 17F shown when the gear st3 of the first upper arm 73Ca and the gear st4 of the first lower arm 73Cb although an external force F is applied to one side of the display device, the angle HLA between the top arm 73a and the lower arm 73b not to be changed. Accordingly, damage attributable to the inclination of the display panel can be prevented.

With reference to 17G can become one side of the first upper and lower arms 73Ca and 73Cb in one direction to the second upper and lower arms 73Fa and 73Fb move out. That is, the width of the first upper and lower arms 73Ca and 73Cb can increase. Accordingly, when the link 73 from the front of the display device, the first upper and lower arms 73Ca and 73Cb the second upper and lower arms 73Fa and 73Fb Shield at the front. Alternatively, the first upper arm 73Ca and the second upper arm 73Fa superimposed. Alternatively, the first lower arm 73Cb and the second lower arm 73Fb superimposed.
