摘要

PURPOSE: A mobile communication terminal having an appearing and disappearing type security filter is provided to selectively narrow a viewing angle of a display unit or return to an original state of the viewing angle. CONSTITUTION: A security filter is contained in a filter housing mounted at one side of a display unit(200), and covers the display unit(200) by being drawn through an open one side of the filter housing. A locking knob is protruded at an end of the security filter toward the inside of a mobile communication terminal to face the display unit(200). The first locking area is formed at one side of the display unit(200) to insert the locking knob. The first locking area fixes the locking knob in a state that the security filter is contained in the filter housing. The second locking area(120) is formed at the other side of the display unit(200) to insert the locking knob. The second locking area(120) fixes the locking knob in a state that the security filter is drawn to the front.
