Patent ID: 7932109

Claim:
A method of manufacturing an organic EL display, comprising: providing a display substrate having a substrate, at least two linear banks arranged on the substrate in parallel, at least two pixel regions arranged in linear regions defined by the at least two linear banks, and a gap between the at least two pixel regions, a height of the gap being greater than heights of the at least two pixel regions; arranging a plurality of ink jet heads adjacent to one another at an edge of the substrate, the edge being parallel to a line direction of the at least two linear banks, the plurality of ink jet heads each including at least two nozzles aligned in a row at a predetermined pitch, ink containing an organic light-emitting material supplied to the at least two nozzles, the row of the at least two nozzles of each of the plurality of ink jet heads being inclined with respect to the line direction, at least one of the at least two nozzles of a first ink jet head of the plurality of ink jet heads overlapping with at least one of the at least two nozzles of a second ink jet head of the plurality of ink jet heads when viewed in a moving direction of the plurality of ink jet heads, the first ink jet head and the second ink jet head being adjacent to one another; and moving the plurality of ink jet heads relative to the display substrate in a direction perpendicular to the line direction of the at least two linear banks and discharging the ink from the at least two nozzles to apply the ink to each of the linear regions to form a linear applied film that covers the gap and the at least two pixel regions arranged in each of the linear regions.
