摘要： PURPOSE: An organic electroluminescent device having high colorimetric purity is provided to improve the color purity by forming an adjustable organic electroluminescent layer. CONSTITUTION: The organic electroluminescent device having high colorimetric purity comprises a transparent substrate, an electroluminescent layer, a metallic electrode layer, a hole transport layer, and an electron transport layer. The electroluminescent layer has blue electroluminescent material and doping material whose band gap is over the 2.65 eV. An indium tin oxide(ITO) is coated on a glass substrate to form the transparent substrate. The hole transport agents include N,N'-diphenyl-N,N'-bis(3-methylphenyl)-1, 1'-diphenyl-4,4'-diamine(TPD).
