Abstract: It is an object of the present invention to provide a portable telephone in which a display portion can be used as a mirror and electric power can be saved under a key locked state. In the telephone according to the present invention, in a front surface of a display portion (10), a panel (8) that is brought into a transparent state when voltage is not applied thereto, and is brought into a mirror surface state when voltage is applied is arranged. When the telephone is set to a key locked state, the panel (8) is brought to the mirror surface state and the display of the display portion (10) is turned off. Under a specific condition that, for instance, a call is received in the key locked state, the panel (8) can be suitably brought to the transparent state and the display of the display portion (10) can be turned on. Under a key unlocked state, while any key is operated, at least the panel (8) is brought to the transparent state and the display of the display portion (10) is turned on.

Abstract: The invention aims at providing electronic apparatus having a mirror which functions in an arbitrary operating state and electronic apparatus which attains low power consumption while serving as a mirror. A light reflective panel(12) whose reflectivity change with the value of a voltage applied is arranged on an LCD(30) of the display (10) of the electronic apparatus; the reflectivity of the light reflective panel(12) is increased and the panel is used as a mirror in a predetermined state where an LCD(30) is not used, such like a portable cell phone(100) performs a incoming call processing, while the reflectivity of the light reflective panel(12) is decreased to place the light reflective panel(12) in the transmittance state so that the LCD(30) may be used. It is thus possible to allow the display(10) provided with the light reflective panel(12) to function as a mirror.
