A liquid ejecting device includes a nozzle group formed by aligning nozzles that eject a liquid, and a liquid ejecting head that ejects liquids from the nozzles based on ejection serial data that represents ejection or non-ejection of each nozzle of the nozzle group. The liquid ejecting head ejects a liquid to a landing target while the liquid ejecting head and the landing target are relatively moved in a second direction that is perpendicular to a first direction in which the nozzles are aligned. The liquid ejecting device further includes a meandering correction pattern forming unit that forms a meandering correction pattern along the second direction in a margin outside the regulated landing area of the landing target and a meandering correction pattern detecting unit that detects the meandering correction pattern formed in the landing target by the meandering correction pattern forming unit.
