Patent number: 8927114Abstract: A layer included in an electroluminescent element is required to be thickened to optimize light extraction efficiency of the electroluminescent element and to prevent short-circuit between electrodes. However, in a conventional element material, desired light extraction efficiency cannot be accomplished since drive voltage rises or power consumption is increased as the element material is thickened.

A composite layer included in an element is formed using the composite as an element material. The composite layer is arranged between a first electrode and a light emitting layer or between a second electrode and a light emitting layer. The composite layer has high conductivity; therefore, drive voltage does not rise even if a film thickness is increased.Type: GrantFiled: November 24, 2005Date of Patent: January 6, 2015Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Ryoji Nomura, Satoshi Seo, Hiroko Abe, Takako Takasu, Hideko Inoue, Hisao Ikeda, Daisuke Kumaki, Junichiro Sakata
