摘要： A display device 1 includes light emitting sections 36, 37 of different luminous colors disposed between anode and cathode electrodes, current control units 34, 35 for controlling currents supplied to the light emitting sections 36, 37 to desired current levels, respectively, and an emergency power supply for supplying a current to the current control units 34, 35 in an emergency in which a commercial power source does not perform a desired function. When operated by the emergency power supply, the current control units turn on and off the light emitting sections 36, 37 of different luminous colors such that they are turned on during different periods of time. When the emergency power supply is used, the display device 1 controls turning on of the planar light emitting element using an organic EL light emitting element depending on luminous colors thereof, thereby suppressing the power consumption of the emergency power supply.
