Provided is a driving method of an organic EL light-emitting part which optimizes mobility correction processing of a transistor for a drive circuit according to luminance. The driving method of the organic EL light-emitting part performs preprocessing[TP(5)1], threshold voltage cancel processing[TP(5)2]and write processing[TP(5)6]using the drive circuit (11) composed of a drive transistor TDrv, a video signal write transistor TSig and a capacitor part C1 having a pair of electrodes (both of the ends of which correspond to a first node ND1 and a second node ND2). Between the threshold voltage cancel processing and the write processing, the variable correction voltage of a value depending on the video signal voltage VCor VSig is applied to the first node ND1, and a potential higher than that of the second node ND2 in the threshold voltage cancel processing is applied to the drain area of the drive transistor TDrv to raise the potential of the second node ND2 according to the characteristic of the drive transistor TDrv.
