Title:
ORGANIC ELECTROLUMINESCENT ELEMENT
Document Type and Number:
Japanese Patent JP3825725
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve carrier property in a carrier layer or a light emitting layer and improve light emission characteristics and service life of an organic electroluminescent element.
SOLUTION: In this organic electroluminescent element provided with the carrier layer and the light emitting layer composed of an organic material between a hole injected electrode and an electron injected electrode, dopant for carrying is doped in the carrier layer and/or dopant for carrying or excited energy moving is doped in the light emitting layer.
