| 主权项 | 1. An organic light-emitting device comprising: a first electrode; a second electrode; and an organic layer interposed between the first electrode and the second electrode, the organic layer comprising an electron transport layer and an emission layer different in composition from and adjacent to the electron transport layer, wherein the material with the highest weight proportion in the emission layer and the material with the highest weight proportion in the electron transport layer are the same material, wherein the material is bis(10-benzoquinolate) beryllium, bis(2-methyl-8-quinolinoato)(p-phenylphenolato)aluminum(III) (BAlq), bis(2-(2-hydroxyphenyl)benzothiazolate)zinc (ZnBTZ), or bis(2-(2-hydroxypenyl)benzoxazolate)zinc(ZnPBO). | ||
