Embodiment 1
[0083] Embodiment 1: the preparation of organic EL display
[0084] Set the resistance to 15Ω / cm 2 The indium tin oxide (ITO) glass substrate (obtained from Coming Co.) was cut into a size of 50 mm × 50 mm × 0.7 mm, ultrasonically cleaned in isopropanol, and then cleaned in pure water for 5 minutes each time , cleaned with UV ozone for another 30 minutes, and used as the anode.
[0085] Formed on the anode with a thickness of The hole injection layer of IDE 406 (obtained from Idemitsu Co.). Next, a layer with a thickness of The hole transport layer formed by 4,4'-bis[N-(1-naphthyl)-N-phenylamino]biphenyl (NPB).
[0086] Formed on the hole transport layer with a thickness of The electroluminescent layer formed by the compound (I-1). Next, a thickness of Electron transport layer of Alq3. LiF and Al are sequentially and Thickness of 2000 is deposited on the electron transport layer by vacuum deposition method to form the electron injection layer and cathode, s...
