1. A mobile terminal comprising:
a first frame;
a second frame slidably-movable with respect to the first frame in a first direction or in a second direction opposite to the first direction;
a slide frame placed at a rear side of the second frame, and slidably movable with respect to the second frame at the rear side of the second frame according to whether the second frame slides in the first direction or in the second direction;
a flexible display unit comprising:
a first region directly coupled to a front side of the first frame,
a second region coupled to a rear side of the slide frame such that the first region and the second region face opposite sides of the mobile terminal, and
a third region positioned between the first region and the second region, wherein the third region comprises a curved portion rolled in the second frame and connects a front portion of the flexible display unit placed at a front side of the mobile terminal and a rear portion of the flexible display unit placed at a rear portion of the mobile terminal;
a driving unit providing a force to control a slide movement of the second frame;
a linear guide positioned between the first frame and the second frame, wherein the linear guide guides a movement of the second frame in the first direction or in the second direction; and
a support frame coupled to a rear side of the third region of the flexible display unit and being bendable according to deformation of the third region of the flexible display unit,
wherein the support frame includes a plurality of grooves formed on a rear surface of the support frame,
wherein the plurality of grooves of the support frame extend in a third direction that is different from the first and second directions, and
wherein a width of a groove of the plurality of grooves that is located at a bent portion of the support frame is smaller than a width of a groove of the plurality of grooves that is located away from the bent portion1
wherein the first frame includes:
a first front portion to be coupled with the first region of the flexible display unit and a first rear portion spaced apart from the first front portion in a rearward direction, wherein the mobile terminal further comprises:
an electronic component disposed between the first front portion and the first rear portion; and
a separating plate for covering a front side of the electronic component, and wherein the second frame includes:
a second front portion positioned at a rear side of the first front portion and configured to move between the first front portion and the separating plate; and
a second rear portion for covering a portion of a rear side of the first rear portion.
