Abstract:
A method of manufacturing an organic electroluminescence display panel including: preparing a substrate; forming pixel electrodes arranged in a matrix above the substrate; forming parallel column banks above the substrate in spaces between the pixel electrodes in a row direction; forming functional layers including organic light emitting layers in gaps between the column banks, including causing relative motion in the row direction between the substrate and a head provided with nozzles arranged along a column direction while ejecting ink from selected nozzles among the nozzles to supply a set of the gaps with an ink including an organic material; and forming a counter electrode above the functional layers. Among the set of the gaps, nozzle patterns of the selected nozzles for a gap differ between a first gap and a second gap in a sequence in the row direction of the set.
