Liquid Ejecting Head Unit and Liquid Ejecting Apparatus
First Claim
1. A liquid ejecting head unit comprising:
- a first nozzle group including a plurality of nozzles;
a second nozzle group including a plurality of nozzles different from the nozzles of the first nozzle group;
a first flow path substrate including a first pressure chamber group including a plurality of first pressure chambers that eject a liquid from the nozzles of the first nozzle group upon being subjected to a pressure;
a second flow path substrate including a second pressure chamber group including a plurality of second pressure chambers that eject a liquid from the nozzles of the second nozzle group upon being subjected to a pressure, the second flow path substrate being different from the first flow path substrate; and
a supply substrate including a first liquid supply path through which the liquid is supplied to the first pressure chamber group, and a second liquid supply path through which the liquid is supplied to the second pressure chamber group, the supply substrate being stacked on the first flow path substrate and the second flow path substrate, on the side of the nozzles.
