N2 - Novel fabrication process of self-aligned bank formation of organic electroluminescent devices using direct ink-jet printing (D-IJP) method has been investigated poly(9-vinylcarbazole) as hole transport material, 2,5-bis(1-napthyl)-1,3,4-oxadiazole as electron transport material, and coumarin 6 as emission material are dissolved into 1,2-dichloroethane and printed on insulating material of polymethylmethacrylate. Blue emission with emission peak at 450 nm has been obtained and this emission spectrum is obviously different from spin coated device structure of ITO/PVCz+BND+C6/LiF/Al. Maximum luminance of the newly developed device is 3,200 cd/m2 at current density of 120 mA/cm2. As a result of atomic force microscope observation, several hundred nanometer-sized domains are observed.
