A pixel driving device has a voltage impressing circuit (14) that outputs a reference voltage (Vref) that exceeds a threshold voltage (Vth) of a drive transistor (T3), a voltage measurement circuit (114), and a property parameter acquisition circuit (16) that acquires a property parameter related to an electronic property of a pixel. The pixel driving device impresses the reference voltage on the pixel that has an electroluminescent light emitting element (101) and the drive transistor. The voltage measurement circuit acquires voltage of a signal line (Ld), as measured voltages, after each of a plurality of the settling times elapsing from the time when the reference voltage is cut. The property parameter acquisition circuit acquires, as property parameters, the threshold voltage and a current amplification factor of drive transistor based on values of a plurality of measured voltages acquired by the voltage measurement circuit.
