A liquid ejection device of the invention is constructed to eject a liquid to an ejection object. The liquid ejection device has a dot data generator configured to generate dot data from given image data, where the dot data represents a dot creation state in each pixel set on the ejection object. The liquid ejection device also has a liquid ejector equipped with a nozzle array including multiple nozzles aligned in a specific direction substantially perpendicular to a scanning direction. The liquid ejector makes multiple scans of the nozzle array in the scanning direction in a common printing area according to the generated dot data and ejects the liquid to the ejection object to create dots.
