PURPOSE: A mobile communication terminal mounting dual LCD screens is provided to retrieve menus on a supplementary LCD screen attached to an external side of a folder by using a supplementary key of the mobile communication terminal, and to display various information on the supplementary LCD screen, thereby enabling a user to confirm the information without opening the folder. CONSTITUTION: A supplementary key(42) is attached to an external side of a mobile communication terminal in order to input a user command for retrieving menus as confirming text messages. A pressing sensor(43) senses that the supplementary key(42) is pressed. A movement sensor(44) senses that the supplementary key(42) moves in vertical direction. A controller(47) displays various text message information and contents on the retrieved menus on a main LCD screen(45), senses that the supplementary key(42) is pressed or moves through the pressing sensor(43) and the movement sensor(44), and displays the text message information and the contents on a supplementary LCD screen(46).
