Abstract: Disclosed is a mobile phone in which a main liquid crystal display and a sub-liquid crystal display are disposed parallel to each other in side by side relation. The folder-type mobile phone has dual outer liquid crystal displays and includes a body housing and a folder which can be opened from the body housing. The mobile phone includes a main liquid crystal display provided in the lengthwise direction of the body housing, a sub-liquid crystal display provided in the lengthwise direction of the folder, and a hinge unit rotatably connecting the folder to the body housing. The hinge unit disposes the main liquid crystal display and the sub-liquid crystal display to be parallel to each other in side by side relation by rotating the folder about a hinge axis. Thus, the folder is situated remote from the body housing in the lengthwise direction of the body housing.
