An organic electroluminescent display device includes a gate line receiving a gate signal, a data line crossing the gate line, the data line receiving a data signal, a switching thin film transistor switching the data signal according to the gate signal, a driving thin film transistor connected to the switching thin film transistor and receiving the data signal, a power line supplying a current to the driving thin film transistor, an organic electroluminescent diode connected to the driving thin film transistor, and a pre-charge element inputting a pre-charge voltage to the data line before the data line receives the data signal.
