Mobile terminal including flexible display

A mobile terminal comprising:

• a body including a first frame and a second frame slidably coupled to a rear surface of the first frame with respect to a first direction or a second direction;
• a flexible display including a first area coupled to a front surface of the first frame, and a second area having a position that varies with respect to a front surface or a rear surface of the body when a size of the body is changed;
• a plurality of reinforcing ribs protruding from the rear surface of the first frame and extending along the first direction;
• a plurality of supports protruding from a front surface of the second frame and located between respective reinforcing ribs of the plurality of reinforcing ribs;
• and
• a driver configured to move the first frame along the first direction or the second direction with respect to the second frame to adjust the size of the body,
• wherein the driver includes:
• a motor housing fastened to the second frame;
• a motor packaged in the motor housing;
• a pinion gear packaged in the motor housing and rotatable by a driving force of the motor;
• a rack gear located at the first frame and extending along the first direction, the rack gear configured to move linearly by the driving force of the motor, which is delivered through the pinion gear;
• and
• a rack gear guide formed at the motor housing and configured to guide the linear movement of the rack gear.
