Patent ID: 8118412

Claim:
A liquid ejecting head comprising: a flow passage forming substrate that includes a plurality of pressure generating chambers juxtaposed to each other and each in communication with a nozzle for ejecting droplets; and piezoelectric elements disposed on the flow passage forming substrate with a diaphragm interposed therebetween, the piezoelectric elements including a lower electrode, a piezoelectric layer, and an upper electrode, wherein the piezoelectric layer tapers downward at its ends, the lower electrode has a width smaller than the width of each of the pressure generating chambers, the piezoelectric layer has a larger width than the lower electrode to cover end faces of the lower electrode, the diaphragm has a top layer formed of a titanium oxide (TiO x ) insulator film, the lower electrode has a top layer formed of a lanthanum nickel oxide (LaNi y O x ) orientation control layer, and the orientation control layer and at least part of the piezoelectric layer disposed on the orientation control layer are formed of perovskite crystals having a (113) preferred orientation.
