摘要

PURPOSE: A device for determining a waveform, a method for determining a waveform, a liquid drop ejector, a method for ejecting liquid drop, a process for depositing a film, a method for fabricating a device, an electro-optical device, and an electric apparatus are provided to improve stability of a liquid droplet. CONSTITUTION: A waveform determining device includes a measuring unit, and a waveform determining unit. The measuring unit(150) measures a viscosity and a mass of a droplet ejected from an ejecting head for ejecting a droplet according to a drive waveform. The waveform determining unit determines the drive waveform to be supplied to the ejecting head on the basis of the viscosity and the mass of the droplet measured by the measuring unit(150). The measuring unit(150) includes a piezoelectric element(132), a resonance resistance value obtaining unit, and a frequency change measuring unit. The piezoelectric element(132) applies an electrode to voltage and vibrates the piezoelectric element.
