ABSTRACT:
A liquid droplet discharge apparatus that discharges liquid droplets onto a work includes a liquid container that contains liquid, a head that discharges the liquid droplets, and a liquid supply device that is disposed between the liquid container and the head and that supplies the liquid from the liquid container to the head. The liquid supply device includes a first tube connected between the liquid container and the head that supplies the liquid, a second tube surrounding an outer circumference of the first tube, and a fluid circulating unit that contains deaerating fluid in a space defined between the first tube and the second tube to circulate the deaerating fluid while deaerating gases contained in the deaerating fluid to outside the second tube through the second tube.
