Driving method of a display device employing electro-light-emitting elements and the same display device
 A driving method of a display device which includes cathodes formed by plural stripe-lines and anodes across the cathodes and formed by plural stripe-lines as well as a light-emitting layer provided between the cathodes and anodes. Firstly, illuminate a first light-emitting element connected to a first cathode, secondly, in order to illuminate a second light-emitting element connected to a second cathode, run electric current into the second element. In this case, remove part of stored charges in the second element and leave charges in at least one light-emitting element other than the second element, then run electric current into the second element. This driving method allows the display device to reduce the power consumption.
