Claim 8:
9. The display device of claim 1, wherein the first magnetic body comprises a magnetic fluid, and the first resisting force generation unit comprises a second magnet;
the first magnetic module further comprises a second housing, at least the magnetic fluid is located in the second housing, and the second magnet is secured to the second housing;
in the first folded state, the second magnet is located on a side of the magnetic fluid facing away from the second magnetic body, a magnetic field direction generated by the second magnet and a magnetic field direction generated by the second magnetic body are the same, and a magnetic field intensity of the second magnet is smaller than a magnetic field intensity of the second magnetic body; and
during the magnetic attraction movement, the magnetic fluid flows towards the second magnetic body under an action of the first attractive force.
