Abstract: A mobile terminal includes a first frame, a second frame slidably-movable in a first direction or in a second direction opposite to the first direction from the first frame, a slide frame movable in the first direction or in the second direction with respect to the second frame, a flexible display unit including a first region coupled to the first frame, a second region coupled to the slide frame, and a third region positioned between the first region and the second region and bent while surrounding the second frame, a driving unit disposed to be positionally biased in a third direction perpendicular to the first direction, wherein the driving unit provides a force to the second frame to move, and a linear guide positioned between the first frame and the second frame and guiding the movement of the second frame in the first direction or in the second direction. The mobile terminal may improve durability of the flexible display unit by not restricting a point where the flexible display unit is bent to a specific position.
