ABSTRACT:
A driving circuit for an electroluminescence device including a plurality of driving electrodes provided on at least one electroluminescence layer, a common electrode oppositely arranged to the driving electrodes with the electroluminescence layers interposed therebetween and commonly conducted, a common voltage supplying unit for applying a common pulse voltage to the common electrode, a luminescence voltage supplying unit for supplying a luminescence pulse voltage to the driving electrodes, and a non-luminescence voltage supplying unit for supplying a non-luminescence pulse voltage to the driving electrodes, wherein a timing in which the voltage applied to the electro-luminescence layer is zero voltage at a leading edge or a trailing edge of a wave form of the common pulse voltage, is utilized so that all of the electroluminescence layer are discharged in synchronization with each other to prevent generation of a spike pulse, whereby electroluminescence with high brightness can be obtained.
