A portable electronic device (1) has a construction in which a first housing (10) and a second housing (11, 401) are capable of being opened and closed and a display (13) is mounted on an inner side of the first housing. A partial display area (14) of the display (13) is in a visible state even if the second housing (11, 401) is closed, and the full display area becomes in a visible state when the second housing is opened. An open/close state of the housings is detected by an open/close detector (15) mounted on the first housing or the second housing. It may be detected by a user operating a predetermined key (16). According to the detected open/close state, a displaying area of the information is changed between the partial display area (14) and the full display area. At the open state, the information is displayed in the full display area. At the closed state, the information is displayed in the partial display area (14). <IMAGE> |
