This invention provides a means for suppressing streaks of light emission in an organic EL display having an organic light-emitting layer formed by coating by an ink jet method. A manufacturing process of the organic EL display of this invention includes: preparing a display substrate having two or more linear banks in parallel to each other, and two or more pixel regions arranged in a region between the linear banks; arranging an ink jet head such that the alignment direction of nozzles and the line direction of the linear banks are in parallel; and relatively moving the ink jet head in a direction perpendicular to the line direction of the linear banks and discharging the ink from the nozzles to apply the ink to every region defined by the linear banks.
