Abstract

See full text

A portable telephone has a telephone body (1) with a first liquid crystal display (2) formed on the frontal face of the telephone body, a swingable plate (4) connected by a hinge (3) to one of lateral edges of said body (1), and a second liquid crystal display (5) formed in and disposed on the swingable plate (4). The second crystal display (5) will be at its exposed position to face backwards when the plate (4) is at its closed position folded back in a close contact with the rear face of the telephone body (1), and the swingable plate (4) can pivot forwards so that the second display (5) faces the same direction as the first display (2). The portable telephone of the invention can be used as it is to serve as an ordinary portable telephone, with its main liquid crystal display (2), but its swingable plate folded back on the back of its body may be put into a reversed position so that its supplementary display cooperates with the main display to form an enlarged area for displaying any information of a large volume such as obtained through INTERNET or the like.
