Patent ID: 8866163

Claim:
A white organic electroluminescence device for lighting devices, comprising: an anode electrode; a cathode electrode; a hole transport layer arranged between the anode electrode and the cathode electrode; an electron transport layer arranged between the anode electrode and the cathode electrode; and a light emission layer into which holes and electrons are injected from the hole transport layer and the electron transport layer, the light emission layer arranged between the hole transport layer and the electron transport layer, wherein said light emission layer comprises a blue region emission layer, a red region emission layer, and a green region emission layer, wherein the emission layers are configured to emit white light for illumination composed of blue, green and red colors each having an emission peak, and a wavelength of the emission peak of the blue color ranges from about 445 nm to about 455 nm, and wherein the blue region emission layer is made of TBP (2,5,8,11 -tetra-t-butylperylene) or sty-NPD, the red region emission layer is made of PQ 2 Ir(acac), and the green region emission layer is made of Ir(ppy) 3 or C545T (10-1,3-benzothiazol-2-yl)-1,1,7,7-tetramethyl-2,3,6,7-tetrahydro-1H,5H,11H-pyrano[2,3-f]pyrido[3,2,1-ij]quinoline-11-one).
