An Electroluminescent display device is designed not to display residual images due to electric charges stored in electroluminescent pixels or to make them invisible, when the device is turned on again. The stored charges are eliminated at the time a normal display on the panel is turned off at an end of an operation, by scanning pixels at least one time while giving a non-activating data voltage thereto. Alternatively, upon turning on the panel, pixels which were activated in a previous use are all lit at least one time, thereby making the residual images invisible. Thus, the residual images stored in a previous operation are not shown or made invisible when the electroluminescent display device is turned on next time.
