In a method for manufacturing an organic EL display panel including: preparing a substrate; forming pixel electrodes in a matrix of rows and columns; forming banks extending in a column direction at least between the pixel electrodes in a row direction; forming a first light emitting layer by applying an ink including a light emitting material in a first gap selected from a plurality of gaps between the banks; forming a second light emitting layer by a vapor deposition method to be continuous above both the first light emitting layer and the pixel electrodes in a second gap adjacent in the row direction to the first gap; and forming a counter electrode above the second light emitting layer, a height of portions of the banks adjacent to the second gap is made to be greater than a height of portions of the banks adjacent to the first gap.
