A mobile terminal includes: a display unit that displays information; and a frame that fixedly surrounds the display unit and is fixed to a terminal case, wherein the frame includes at least one supplementary module mounting unit allowing a supplementary module that performs a different function from that of the display unit to be integrally mounted thereon. A supplementary module different from the display unit is integrally mounted on a frame constituting a display assembly, so handling and assembling can be facilitated and production cost can be reduced.
