A liquid discharge apparatus includes: a head unit that has a nozzle array in which a plurality of nozzles are arranged, that discharges a liquid from each of the plurality of nozzles, and that causes liquid columns to extend downwardly; a liquid droplet generating unit that irradiates at least the two liquid columns with a laser beam in a direction obliquely intersecting with the arrangement direction when viewed from the center of the nozzle array and that separates liquid droplets from the liquid column; and a direction changing unit that applies energy to the liquid droplets and changes flying directions of the liquid droplets.

A liquid discharge apparatus includes: a head unit that has nozzles that discharge a column-shaped liquid; a liquid droplet generating unit that applies cyclically changing energy to positions of the column-shaped liquids discharged from the nozzles, which are separated from the nozzles, and that generates liquid droplets; and a direction changing unit that changes a flying direction of at least some liquid droplets of the generated liquid droplets.

A liquid discharging head includes a discharge port that discharges a liquid, a pressure chamber that communicates with the discharge port, and an energy generating element that is disposed in the pressure chamber. In the liquid discharging head, the discharge port is provided with a plurality of projections that project towards a central portion of the discharge port from an inner peripheral edge of the discharge port, and an interval between the projections at a location where the projections are closest to each other is 5 m or less.
