Abstract: An electroluminescence display device comprises a light emitting diode having an anode connected to a node A, and a pixel driving circuit supplying a driving current to the node A and including a node B, a node C and a node D. The pixel driving circuit includes a driving transistor controlled by a voltage supplied to the node B, a first transistor turned on by a first scan signal, supplying a data voltage to the node C, a second transistor turned on by a second scan signal, electronically connecting the node B with the node C, a third transistor turned on by an emission signal, electronically connecting the node D with a node E, a fourth transistor turned on by a C signal, supplying a reference voltage to the node E, a storage capacitor connected to the node B and the node D, and a capacitor connected to the node C and a reference voltage line to which the reference voltage is supplied. In this case, the emission signal includes a pulse overlapping with the first scan signal and the second scan signal, and the C signal includes a pulse overlapping with the emission signal without overlapping with the first scan signal and the second scan signal.
