<P>PROBLEM TO BE SOLVED: To provide a correction method of a nozzle ejection rate capable of calibrating variations in weight of droplets ejected from a nozzle with high accuracy, and further to provide an ejection method of the droplets using the correction method thereof and a manufacturing method of an organic EL element. <P>SOLUTION: A correction method of a nozzle ejection rate in one embodiment performs correction amount calculations by the number of nozzle row units in a stepwise manner such that a total value C of weight of droplets of nozzle row units after correction and weight of droplets of other nozzle row units performing ejection to an ejection area becomes a predetermined amount B from a difference between a total value A of weight of all droplets ejected to the ejection area when weight correction of droplets ejected from a nozzle is not performed and a predetermined amount B set beforehand. Correction as described above may be performed by using ejection units or scan units as a reference. <P>COPYRIGHT: (C)2013,JPO&INPIT |
