    • There is disclosed an electro-luminescence display device that is adaptive for preventing picture quality deterioration by operating a thin film transistor for an electro-luminescence cell drive at a non-saturation area to compensate a threshold voltage, and a driving method thereof. An electro-luminescence display device according to an embodiment of the present invention includes an electro-luminescence cell connected between a first supply voltage source and a ground voltage source to emit light by a current supplied from the first supply voltage source; a cell driver formed every intersection of gate lines and data lines and connected between the first supply voltage source and the electro-luminescence cell to control a current flowing in the pixel cell; and a pulse supplier supplies to the electro-luminescence cell a pulse amplitude modulation signal which is divided to have N (N is a natural number) numbers of different voltage levels from each other, and wherein the driving thin film transistor operates at the non-saturation region.
