After a sampling transistor is turned ON at a first timing when a control signal has risen, during a sampling period from a second timing when a video signal has risen from a reference potential to a signal potential to a third timing when the control signal has fallen and is turned OFF, the sampling transistor samples and writes the signal potential in a holding capacitance, and negatively feeds back a current flowing into a drive transistor during the sampling period to the holding capacitance and applies mobility correction of the drive transistor on the written signal potential. A signal driver adjusts the second timing for the video signal supplied to respective signal lines to correct a backward shift of the third timing due to a transmission delay along a scanning line of the control signal output from the control scanner.
