The method for manufacturing organic EL display panel as set forth in claim 16 wherein at least one of said reference parameters other than said ithreference parameter is increased or decreased by a predetermined amount and one or both of the upper and lower limits of the ithreference parameter are changed according to the amount increased or decreased in said parameter determining step, and the ithreference parameter is increased or decreased within the range of upper and lower limits. 18. The method for manufacturing organic EL display panel as set forth in claim 15 wherein the (i+1)threference parameter is increased or decreased when the difference between said reference volume and said unit volume is more than the predetermined threshold even if the ith(i≤n) reference parameter is increased or decreased to its upper or lower limit in said parameter determining step. 19. The method for manufacturing organic EL display panel as set forth in claim 12 wherein said reference parameters modified to minimize the difference between said reference volume and said unit volume are determined as the parameters of the driving signal to be applied to the ink jet head, when the reference parameters cannot be modified so that the difference between the reference volume and the unit volume is equal to or lower than the predeter
