Abstract: Disclosed herein is a mobile terminal including a first frame, a second frame, a slide frame movable with respect to the second frame in a first direction or a second direction, a flexible display including a third region bent to surround the second frame, and a rolling plate attached to a rear of the flexible display. The second frame includes a side portion at an end thereof facing in a third direction perpendicular to the first direction, and a slide rail formed on the side portion. The rolling plate includes a plurality of support bars extending in the third direction and arranged in the first direction, and a slide hook protruding from an end of each of the support bars and movably inserted into the slide rail. The terminal may maintain the display in a flat state by preventing the display from being separated when the second frame is moved.
