ABSTRACT:
A portable terminal device according to the present invention, for example a cellular phone, comprises a plurality of liquid crystal displays (LCDs) and a display switching controller. When the main LCD is out of order, the controller causes information that is to be displayed on the LCD, to be displayed on another LCD. The portable terminal device can comprise a malfunction detection unit for detecting a malfunction in the main LCD. The detection unit verifies data to be displayed in a driver circuit, or detects a current value in the circuit. The controller controls display on a basis of a signal from the detection unit. Information to be caused to be displayed on another LCD can be set in advance, or can be set by a user.
