PROBLEM TO BE SOLVED: To provide a liquid-droplet ejection device capable of preventing the generation of liquid-droplet flight deflection and mist even if the viscosity of liquid material is high and the size of the ejected liquid-droplet is relatively large, and a manufacturing method of an electro-optics apparatus using the liquid-droplet ejection device. SOLUTION: With a drive signal COM impressed to a piezoelectric element in the liquid-droplet ejection device, a contractile element P1 for ejection preparation, which is equipped with a contraction composition P11 for making a pressure generating chamber contracted to the extent of the liquid-droplet not being ejected from an initial state and a hold composition P12 for holding the contraction state of the pressure generating chamber, is impressed to the piezoelectric element before an inflatable ejection element P2 for expanding the pressure generating chamber to eject the liquid-droplet from the chamber. In a second hold element P5 for holding the contraction state of the pressure generating chamber when ejecting the liquid droplet, a time span t17 for holding the pressure generating chamber in the contraction state is established to be more than a Helmholtz resonance period in the pressure generating chamber.
