The image signal output section switches the display of the first image and the display of the second image in synchronization with a switching of the emitting of the light-emitting region and non-emitting of another light-emitting region of the organic electroluminescence device by the light-emission control section.

Abstract: The supply voltage to a driving circuit (100) and LCD (200) generated by a power supply circuit (350) is controlled to be periodically turned on and off during a power save mode, using a timer circuit (260) or timer such as a counting circuit. In this manner, during the power save mode, the power consumption can be reduced by turning off the power supply, and, at the same time, the display can be periodically shown without any further manipulation. By suspending the output of the gate selection signals to the display panels before the control to turn off the power supply, the display immediately before the turn off operation can be maintained even after the power supply is turned off.
