Method for luminescent layer formation and organic electroluminescent device

A method for the formation of a luminescent layer in an organic electroluminescent device comprising opposed electrodes, a luminescent element layer provided between the electrodes, the luminescent element layer comprising at least a luminescent layer, the method comprising the steps of:

• filling an ink, for a luminescent layer, comprising at least an organic luminescent material into cells in a gravure form;
• allowing a blanket to receive the ink for a luminescent layer from the cells;
• and
• then transferring the ink for a luminescent layer on the blanket onto a luminescent layer forming face, wherein
• the blanket has a resin film having a surface tension of not less than 35 dynes/cm as a surface layer,
• the ink for a luminescent layer has a viscosity (ink temperature 23° C.) in the range of 5 to 200 cP as measured at a shear rate of 100/sec, and
• a solvent having a surface tension of not more than 40 dynes/cm and a boiling temperature in the range of 150 to 250° C. is used in the ink for a luminescent layer.
