Abstract
The present invention provides a manufacturing method for forming an organic electro-luminescent device by forming a homogeneous light emitting layer which does not incur the phase separation. The light emitting layer is formed by discharging ink compositions composed of at least two electro-luminescent materials on the substrate following the order which starts with an ink composition which has the fewest number of organic electro-luminescent materials or which is most difficult to be phase separated.
