Liquid droplet discharge apparatus, liquid supply device thereof, electro-optical device, and electronic apparatus

A liquid supply device provided in a liquid droplet discharge apparatus that discharges liquid droplets onto a work, the liquid supply device disposed between a liquid container and a head to supply the liquid from the liquid container to the head, comprising:

• 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.

An electro-optical device manufactured using a liquid droplet discharge apparatus that discharges liquid droplets from a head onto a work,

• wherein a liquid supply device disposed between a liquid container and the head to supply the liquid from the liquid container to the head includes;
• a first tube connected between the liquid container and the head that supplies the liquid;
• and
• a second tube surrounding an outer circumference of the first tube that supplies the liquid, and
• wherein the electro-optical device is manufactured by discharging the liquid droplets from the head onto the work by using 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.
