A resetting period of organic EL elements is divided to a discharge period for discharging residual charges of the organic EL elements and a precharge period for pre-charging the organic EL elements to predetermined potentials. First switch circuits provided for each of R (red), G (green) and B (blue) display colors are turned ON in the discharge period to discharge residual charges of the organic EL elements and second switch circuits provided for each of R, G and B display colors are turned ON in the precharge period to precharge the EL elements to a precharge potential lower than a light emission voltage of the organic EL elements. Values of finally set precharge voltages for R, G and B display colors are made different from each other.
