An organic electroluminescent device has a plurality of sub-pixels formed on an area having crossed over data lines and scan lines. The device includes a preliminary charge driving circuit which discharges each data line during a discharge time of preliminary charge time, and pre-charges the discharged data line by applying pre-charge current during pre-charge time of the preliminary charge time. The device further includes a data driving circuit which applies a data current to the pre-charged data line during a light-emitting time based on input RGB data. A length of pre-charge time is changed corresponding to the RGB data.
