No. 2006-174506, a communication terminal has been proposed in which the following is connected so as to be bendable in the back direction toward the adjacent substantially planar frame. A substantially rectangular flexible display having a flexible visible surface; and a substantially flat communication terminal frame and another housing, wherein two or more substantially flat frames are viewed from a user. A substantially flat frame group that is connected to each other in a lateral direction, and the communication terminal casing has at least a wireless communication unit, an audio input unit, and an audio output unit.

In the communication terminal of Patent Document 1, the size of the screen can be increased, and in the state where the communication terminal is placed on a table or the like, for example, it is not necessary to support by its own hand, and it can be freely held by both hands. Watch the picture in the status.

Further, in the patent document 2 (JP-A No. 10-207389), there has been proposed an image display device comprising: a flexible flat display image display unit having flexibility; and a housing case having a predetermined deployment The contraction mechanism keeps the display surface of the flexible image display unit visible when deployed, and can deform and accommodate the flexible image display unit during contraction.

In the image display device of Patent Document 2, since the display surface of the flexible image display unit is kept visible when the storage case is unfolded, it is possible to provide an image display device which can be easily used in a small-sized electronic device. Show more information by sight. [Prior Art Literature] [Patent Literature]
