The main liquid crystal display device is arranged inside the main screen (21), while the sub liquid crystal display device is arranged inside the sub screen (22). When the lid cabinet (2) is opened, the main liquid crystal display device is arranged. When the lid cabinet (2) is closed on the screen (21), various information such as display of input characters and notification of incoming calls are displayed on the sub screen (22).

  However, in such a foldable mobile phone, since the main body cabinet (1) and the lid cabinet (2) are made of resin, the strength of the cabinet is greatly reduced by making the lid cabinet (2) thinner, for example. Will do. As a result, the lid cabinet (2) is easily deformed by the action of the external force, and the external force acts directly on both liquid crystal display devices, whereby the glass liquid crystal display constituting each liquid crystal display device is formed. There was a problem of cracking.

In order to solve such a problem, there has been proposed a foldable mobile phone in which a cabinet is configured with a metal chassis as a skeleton, thereby increasing the mechanical strength of the cabinet itself (see Patent Document 1).
According to the foldable mobile phone, even if an external force is applied to the cabinet, the cabinet has a large strength, so that the external force does not directly act on the liquid crystal display device inside the cabinet.
