Liquid ejecting head, liquid ejecting device, and liquid ejecting method

The present invention relates to a liquid ejecting head and a liquid ejecting device including a driving circuit with which the number of control signal lines for grouping and dividing a plurality of liquid ejecting mechanisms into a plurality of blocks and dividedly driving the groups of liquid ejecting mechanisms concurrently is reduced, and to a liquid ejecting method by the driving circuit. The driving circuit ( 19 ) includes a phase generating circuit (a phase counter 30 and decoders 31 ) for generating phase signals for dividedly driving the groups of liquid ejecting mechanisms, and a serial/parallel converting circuit ( 32 ) for parallel converting and serially transferring data for dividedly driving the groups of liquid ejecting mechanisms.
