Patent ID: 8124190

Claim:
A method for discharging a liquid material comprising: performing a scan by moving, in a scanning direction, a discharge target having a plurality of film formation areas aligned in the scanning direction and a plurality of nozzles aligned in a nozzle row direction forming a nozzle row with respect to each other, the scanning direction intersecting the nozzle row direction; and discharging a liquid material containing a functional material as droplets from the nozzles onto the film formation area by selectively applying one of a plurality of drive waveforms generated using time division to an energy generation element of each of the nozzles in synchronization with the scan so that each of the film formation areas receives the liquid material discharged from at least two of the nozzles, the discharging of the liquid material including applying a first drive waveform to a first nozzle of the nozzle row associated with the film formation areas and a second drive waveform having a different discharge timing from the first drive waveform to a second nozzle of the nozzle row associated with the film formation areas with the second nozzle being adjacent to the first nozzle, and changing a combination of the first and second drive waveforms selected from the drive waveforms at least once with respect to adjacent ones of the film formation areas aligned in the scanning direction.
