    摘要: The present invention relates to an electroluminescent device. More specifically, the electroluminescent device according to the present invention is comprised of a first electrode; a second electrode; and at least one organic layer(s) interposed between the first electrode and the second electrode; and the organic layer comprises one or more organic electroluminescent compound(s) represented by Chemical Formula (1) as host material: L1L2M(Q)y   Chemical Formula 1 wherein, the ligands, L1 and L2 are independently selected from the following structures: wherein, M represents a divalent or trivalent metal; y is 0 when M is a divalent metal, while y is 1 when M is a trivalent metal; Q represents (C6-C60)aryloxy or tri(C6-C60)arylsilyl, and the aryloxy or triarylsilyl of Q may be further substituted by (C1-C60)alkyl or (C6-C60)aryl. The electroluminescent devices according to the invention exhibit excellent color purity and luminous efficiency.
