1. A mobile terminal comprising:
a first frame;
a second frame configured to slidably move from the first frame in a first direction and a second direction, the second direction being opposite to the first direction;
a metal rolling ball inserted into a side portion of the second frame, and
a magnet provided in an insertion portion of the second frame to apply magnetic force to the rolling ball, the rolling ball being inserted into the second frame,
a flexible display comprising a fixed portion coupled to the first frame, and a variable portion bent in a manner of surrounding the second frame; and
a rolling plate attached to a rear surface of the variable portion of the flexible display,
wherein the second frame comprises:
the side portion positioned at an end thereof facing in a third direction perpendicular to the first direction; and
a slide rail formed on the side portion,
wherein the rolling plate comprises:
a plurality of support bars extending in the third direction perpendicular to the first direction and arranged side by side in the first direction;
and
a slide hook protruding at an end of each of the support bars, and inserted into the slide rail to move along the slide rail,
wherein, when the second frame is moved in the first direction or the second direction, the rolling ball rotates in contact with the first frame.
