A liquid ejection device includes a plurality of nozzles, a plurality of piezoelectric elements, a drive signal generating portion, a selection portion and an ejection testing portion. The nozzles are arranged to eject a liquid. The piezoelectric elements are provided in respective correspondence to the nozzles. The drive signal generating portion is arranged to generate a drive signal which repeats for each of ejection cycles in which the nozzles eject the liquid onto a pixel, there being a plurality of selectable periods provided in the ejection cycles, at least one of the periods being a testing period. The selection portion is arranged to selectively apply the drive signal to the piezoelectric elements in each of the periods. The ejection testing portion is arranged to perform ejection testing of the liquid from at least one of the nozzles to be tested.
