摘要:
There is provided a driving circuit for an EL element which extends the life of the EL element and has improved driving efficiency. A capacitor 11 is parallel-connected to a series circuit 3 formed by an EL element 1 and an inductor 2 to cause harmonic components and a driving frequency lower than the same to pass through the capacitor 11 and the EL element 1, respectively, to extend the life of the EL element and to improve driving efficiency.
