<P>PROBLEM TO BE SOLVED: To provide an organic EL device with high emission luminance. <P>SOLUTION: An organic EL device comprises a substrate, a first insulation film, a second insulation film, a first electrode, a second electrode, and a light-emitting layer. The first insulation film is formed on the substrate, and has a semi-transmitting property with a higher refractive index than the substrate. The second insulation film is formed on the first insulation film, and has a semi-transmitting property with a lower refractive index than the first insulation film. The first electrode is formed on the second insulation film, and has a higher refractive index than the second insulation film. The second electrode faces the first electrode. The light-emitting layer is formed between the first and second electrodes. <P>COPYRIGHT: (C)2012,JPO&INPIT |
