Liquid droplet discharge device

A liquid droplet discharge device including a liquid chamber that is communicated with a discharge opening, and that is supplied with a liquid material, a needle having a tip that is advanced and retracted within the liquid chamber, a drive device that operates the needle to advance and retract, and a displacement magnifying mechanism, the liquid droplet discharge device discharging liquid droplets from the discharge opening, wherein the drive device is constituted by an even number of drive devices disposed in a left-right symmetric relation, the displacement magnifying mechanism includes an elastically deformable U-shaped member having a bottom portion to which the needle is coupled, and the drive devices operate the needle to retract by applying forces acting to move the two ends of the U-shaped member away from each other, and to advance by applying forces acting to move the two ends of the U-shaped member closer to each other.
