Definitions
- an organic EL light emitting element is configured by laminating a cathode made of a metal such as aluminum, an organic layer, an anode made of a transparent alloy such as ITO, and a glass substrate, and includes a light emitting layer in the organic layer.
- the refractive index of the transparent electrode is about 1.8, for example, and the refractive index of glass is about 1.5, for example. Because of this difference in refractive index, light emitted from the light emitting layer is reflected at the interface between the transparent electrode and the glass substrate and at the interface between the glass substrate and the air layer, and finally only about 20% of the light is extracted into the air layer. It is said that it cannot be done.
- Patent Document 1 discloses a light-emitting device in which a refractive material layer made of a highly refractive resin is provided on the upper surface of a glass substrate for the purpose of improving light extraction efficiency.
- FIG. 1 shows a configuration of a light-emitting element 1 that is an embodiment of the present invention.
- the light emitting layer 4c is made of an organic EL material.
- the organic EL material for example, any known material such as a fluorescent material or a phosphorescent material can be applied.
- FIG. 3 shows the second electrode layer 5, the light scattering layer 7, the reflection layer 8, and how the light beams 21 and 22 are reflected and refracted by these configurations.
- the light-emitting element 1 of this example not only the first electrode layer 3 but also the second electrode layer 5 is a light-transmitting electrode layer.
- a light scattering layer 7 is formed on the second electrode layer 5, and a reflection layer 8 is further formed on the light scattering layer 7.
- the light scattering layer 7 includes a plurality of light scattering particles 7b having a high refractive index.
- the light beam 22 from the organic layer 4 is repeatedly reflected and refracted randomly by the reflective layer 8 and the light scattering particles 7 b, and can be incident on the second electrode layer 5 at an angle that can be taken out. Thereby, the extraction efficiency of the light beam 22 to the transparent substrate 2 side can be improved.
- FIG. 4 shows a configuration of the light emitting element 1 that does not include the resin portion 7a.
- the light scattering layer 7 is composed of a plurality of light scattering particles 7b adhered to each other. Similar to the above embodiment, the light scattering layer 7 is formed on the second electrode layer 5, and the reflection layer 8 is formed on the light scattering layer 7. Since the resin portion 7a is not used, the cost can be reduced.
- a first electrode layer 3 made of a light transmissive electrode material such as ITO is formed on a transparent substrate 2 made of a light transmissive material such as glass or a resin film by a film forming method such as sputtering. (FIG. 7A).
- plasma treatment for modifying the surface of the first electrode layer 3 may be performed.
- the efficiency of hole injection into the organic layer 4 formed on the first electrode layer 3 is improved by performing such plasma treatment.
