A drive method of a display device includes the steps of: performing threshold voltage cancel processing at least once, which changes a potential of a second node of a display device toward a potential obtained by subtracting a threshold voltage of a drive transistor from a potential of a first node by applying a given drive voltage to one source/drain region of the drive transistor from a feeding line while maintaining the potential of the first node; and then, performing writing processing which applies a video signal to the first node from a data line through a write transistor, wherein the sum of lengths of periods in which the threshold voltage cancel processing is performed is so set as to be shorter as a frame frequency becomes higher.
