Abstract:
A method of manufacturing organic LED display including ink jet forming a light emitting organic layer, the method comprising:providing a coating liquid comprising (a) an organic material having at least one of conductivity and fluorescence, and (b) at least one low volatile liquid solvent having a vapor pressure of 10 mmHg of less at 20Â° C. and a boiling point lower than a denaturing temperature of the organic material and wherein the low volatile liquid solvent has a boiling point lower than the melting point of the organic material; ink-jet discharging the liquid by an ink-jet technique to form at least one film, and heat drying the film at a temperature not lower than the boiling point of a low volatile liquid solvent contained in the coating liquid, thereby forming the organic layer.
