Claim:
1. A liquid discharge apparatus, comprising: a liquid discharge head comprising: a moving unit configured to relatively move the liquid discharge head and a recording object; and a driving unit configured to drive the pressure generating units, wherein flow paths respectively corresponding to the plurality of pressure chambers adjacent to the supply paths are connected to the supply paths, wherein the driving unit outputs drive signals to the pressure generating units respectively corresponding to the plurality of pressure chambers connected to the supply paths at different timings, wherein the pressure chambers having the flow paths connected to one of the supply paths are provided at vertices of a quadrangle having a center corresponding to a center of the one of the supply paths, wherein, when a plane in which a plurality of discharge ports corresponding to the plurality of pressure chambers are provided is taken as an X-Y plane, and a direction in which the liquid discharge head and the recording object are relatively moved is taken as a Y direction, a flow path corresponding to each of an even number of pressure chambers that sandwich the supply path in an X direction is connected to the supply path, and wherein the driving unit drives, alternately in the X direction, pressure generating units respectively corresponding to the even number of pressure chambers connected to the supply path.
