Patent ID: 8574724

Claim:
An organic electroluminescent device comprising: a light-emitting layer formed between a pair of electrodes by a wet process; and an electron transport layer, the light-emitting layer including: an organic material and a light-emitting material having a crosslinking property; and a first crosslinked layer formed by crosslinking the organic material having the crosslinking property, and arranged at least at an interface of the electron transport layer and the light-emitting layer, the electron transport layer including: an electron transport layer-forming material that has a crosslinking property; a second crosslinked layer formed by crosslinking the electron transport layer-forming material; and an uncrosslinked layer in which the electron transport layer-forming material is not crosslinked, the electron transport layer being formed on the light-emitting layer, the second crosslinked layer being arranged at the interface of the electron transport layer and the light-emitting layer, the uncrosslinked layer being arranged at an interface of the electron transport layer and one of the pair of electrodes, the organic material being of a material expressed as the light-emitting layer material being of a material expressed as the electron transport layer-forming material comprising the following material wherein n is an integer that is equal to, or greater than 1.
