摘要： Disclosed herein is a light emitting element driving circuit including: a capacitive element; a current limiting section limiting a charging current for the capacitive element; a first constant current source stabilizing a discharging current supplied from the capacitive element to a light emitting element; and a switch controlling ON and OFF in supplying the discharging current to the light emitting element. The capacitive element is charged with electricity from the power source circuit in the preceding stage through the current limiting section. Also, the electric charges in the capacitive element are discharged in the form of a given discharging current for the discharging time period, and the light emitting element emits light in accordance with the given discharging current. In this case, the charging current for the capacitive element is limited by the current limiting section in such a way that the current value thereof becomes small.
