PROBLEM TO BE SOLVED: To provide a driving circuit which has a refreshing effect for life- elongation of an organic electroluminescence element. SOLUTION: This is the driving circuit wherein based on the direct-current power source connected between a segment and common at the time of the lighting when the drive voltage is applied, the drive voltage is applied on the organic electroluminescence element to display appointed patterns by light emission at the applied segment point. This has a control circuit to control the application of the property recovery voltage V2 which has the opposite polarity to that of the drive voltage V1 and whose size v2 is smaller than the size v1 of the drive voltage V1. |
