Claim Text:
1. A driving device for a light-emitting element, comprising: a power supply line and a potential line coupled to the light-emitting element, the light-emitting element being connected between the power supply line and the potential line; a control circuit configured to drive at least the power supply line so as to control a voltage between the power supply line and the potential line; wherein the control circuit is configured to: in an emission period of the light-emitting element, sequentially apply an active voltage and an intermediate voltage between the power supply line and the potential line, with a pulse-shaped waveform such that a predetermined luminance duration is obtained in the emission period, and in a non-emission period of the light-emitting element, apply an off-state voltage between the power supply line and the potential line so as to maintain the light-emitting element in a non-emission state.
