The present invention provides a phosphorescent compound represented by chemical formula. In the chemical formula, R1 to R15 are respectively and individually selected from hydrogen, deuterium (D), halogen such as F, Cl, and Br, CF3, a cyano group, a C1 to C18 alkyl group, a C1 to C18 alkoxy group, a C6 or more substituted or unsubstituted aromatic group, a C5 or more substituted or unsubstituted heteroaromatic group, a C1 to C18 amine group, an amine group in which the C6 or more aromatic group is substituted, an amine group in which the C5 or more heteroaromatic group is substituted, a silyl group in which the C1 to C18 alkyl group or the C6 or more aromatic group is substituted, and a silyl group in which the C5 or more heteroaromatic group is substituted. According to the present invention, low quantum efficiency can be improved. |
