Fig. 11 is a schematic diagram of a fifth embodiment of the display device 1 of the present application, wherein the power-on connector 23 is in a storage position. The fifth embodiment is different from the fourth embodiment in that the moving element 26 is connected (or pivoted) in the housing 21. The display device 20 further includes a first magnetic element 27 disposed on the moving element 26.

In this embodiment, the moving element 26 may be an L-shape, one end of the moving element 26 is connected to the upper connector 23, and the first magnetic element 27 is disposed on the other end of the moving element 26.

In this embodiment, the power-on connector 23 can be moved from the connecting position of FIG. 10 to the storing position of FIG. 11 by at least one magnetic device T3. The magnetic device T3 can be used to generate a magnetic force to the first magnetic element 27. When the magnetic force generated by the magnetic device T3 attracts the first magnetic element 27 to move toward the display panel 22, the moving element 26 rotates and drives the power-on connector 23 to move to the storage position.

In the present embodiment, the magnetic device T3 may include a mounting bracket T31 and a second magnetic element T32.
