Abstract:
A liquid ejection device is disclosed. One device includes a plurality of contacts aligned along a first direction. The plurality of contacts are positioned between two piezoelectric-element rows of four piezoelectric-element rows in a second direction orthogonal to the first direction. Each of the two piezoelectric-element rows is closer to a center line of a first substrate with respect to the second direction than each of another two piezoelectric-element rows of the four piezoelectric-element rows in the second direction. Each of a plurality of piezoelectric elements of a four piezoelectric-element rows is individually connected with a corresponding one of the plurality of contacts, respectively. One of the plurality of piezoelectric elements of the another two piezoelectric-element rows connect with a corresponding one of the plurality of contacts.

Claim (Index 7):
A liquid ejection device comprising:\n a first substrate having two pressure-chamber rows, wherein each of the two pressure-chamber rows has a plurality of pressure chambers, each of the two pressure-chamber rows extends along a first direction and each of the two pressure-chamber rows is offset from one another in a second direction orthogonal to the first direction; two piezoelectric-element rows positioned corresponding to the two pressure-chamber rows, respectively, wherein each of the two piezoelectric-element rows has a plurality of piezoelectric elements, each of the two piezoelectric-element rows extends along the first direction and each of the two piezoelectric-element rows is offset from one another in the second direction; a plurality of contacts aligned along the first direction between the two piezoelectric-element rows in the second direction, and a second substrate located opposite to the piezoelectric elements relative to the first substrate, wherein the second substrate has a common liquid chamber communicating with at least one of the two pressure-chamber rows, wherein the plurality of contacts overlap the common liquid chamber when viewed in a third direction in which the first substrate and the second substrate are laminated on one another, wherein the second substrate includes a projecting portion at a wall thereof, wherein the wall defines a portion of the common liquid chamber.
