ORGANIC ELECTROLUMINESCENT ELEMENT AND MANUFACTURING METHOD THEREOF, ORGANIC COMPOUND CONTAINING PHOSPHOROUS AND MANUFACTURING METHOD THEREOF

摘要

An organic electroluminescent element provided with a plurality of organic compound layers sandwiched between an anode and a cathode. The organic electroluminescent element is provided with a hole transporting layer composed of an organic compound insoluble in alcohol solvents, and an electron transporting layer formed on the hole transporting layer by a wet method. The material of the electron transporting layer is an organic compound which contains phosphorus and soluble in alcohol solvents. A method for manufacturing the organic electroluminescent element, the organic compound containing phosphorus and a method for manufacturing such compound are also provided. ® KIPO & WIPO 2007
