ABSTRACT:
A method for manufacturing an organic electroluminescent device includes forming a first electrode and a first carrier transport layer on a substrate having sub-pixels that include a first light emitting area for a first color, a second light emitting area for a second color, and a third light emitting area for a third color, forming a first color light emitting layer in the first light emitting area using a first hydrophobic material, forming a second color light emitting layer in the second light emitting area using a second hydrophobic material, forming a third color light emitting layer in the first, second and third light emitting areas or in the third light emitting area, forming a second carrier transport layer on the third light emitting area; and forming a second electrode on the second carrier transport layer.
