Method for discharging liquid material, method for manufacturing color filter, and method for manufacturing organic EL element
Abstract:
A method for discharging a liquid material includes performing a scan by moving a discharge target having a film formation area and a plurality of nozzles forming a nozzle row, and discharging a liquid material containing a functional material from the nozzles onto the film formation area by selectively applying one of drive waveforms generated using time division to an energy generation element in synchronization with the scan. The method includes applying a first drive waveform to a first nozzle and a second drive waveform having a different discharge timing to a second nozzle with the second nozzle being adjacent to the first nozzle, and setting the combination of the first and second drive waveforms so that the number of the energy generation elements to which the first drive waveform is applied is the same as the number of the energy generation elements to which the second waveform is applied.
