ABSTRACT:
A driving apparatus for a capacitive light emitting element display panel which comprises a driving apparatus for supplying a first predetermined potential to one selected scanning line, supplying a second predetermined potential higher than the first predetermined potential to scanning lines other than the one scanning line, supplying a driving current to a light emission drive line corresponding to a capacitive light emitting element driven to emit light, and supplying a third predetermined potential higher than the first predetermined potential and lower than a light emission threshold voltage to drive lines other than the light emission drive line, wherein the third predetermined potential is generated from a current discharge terminal of a voltage source connected to a predetermined load circuit for supplying a power supply voltage to the predetermined load circuit.
