An electro-luminescence (EL) display device includes an electro-luminescence display panel including a plurality of pixels arranged in a matrix form at pixel areas defined by intersections between gate lines and data lines, each of the pixels having an EL cell connected to a first voltage source and a cell driver, the cell driver connected to a respective one of the gate lines and a respective one of the data lines and connected between a second voltage source and the EL cell, and a pre-charger for pre-charging a storage capacitor in the cell driver into a first pre-charge voltage using a pre-charge voltage source and then floating the respective data line in a pre-charge period prior to an application of a data signal, thereby arriving at a second pre-charge voltage by a discharge of the first pre-charge voltage of the storage capacitor.
