Abstract
A mobile communication terminal having two keypads is provided. A mobile communication terminal comprises a first body having a left keypad installed at the left side of a front surface, and a second body having a display window installed at its left side and a right key installed at its right side, that is movably assembled with the front surface of the first body in the left or right direction. The mobile communication terminal may be used as a bar type communication terminal when the second body is not moved by sliding. If the left keypad of the first body is exposed by sliding down the second body, the two keypads are located at different sides of the display window, and thereby characters may be easily input with both hands. The two keypads arranged at different sides can each be or can both, be provided with a size large enough for individual character input.
