| description | The present invention relates to an organic electroluminescence diode including a dopant compound and a host compound of specific combinations. The organic electroluminescence diode of the present invention can be operated at a lower driving voltage than a diode using a traditional light emitting material, so as to have better luminescence efficiency. Provided in the present invention is the organic electroluminescence diode, including more than one type of the dopant compound represented in the below chemical formula 1, and more than one type of the host compound represented in the below chemical formula 2. In the chemical formula 1: L stands for an organic ligand; R1 through R9 are hydrogen, heavy hydrogen, halogen, a substituted or non-substituted C1-C30 alkyl group, a substituted or non-substituted C3-C30 cycloalkyl group, a substituted or non-substituted C1-C30 alcoxy group, a substituted or non-substituted C6-C30 aryl, or a substituted or non-substituted C3-C30 heteroaryl group; R stands for hydrogen, halogen, a substituted or non-substituted C1-C30 alkyl, or a substituted or non-substituted C3-C30 cycloalkyl group; a is an integer ranging from one through three, and when a is an integer above two, each R can be or cannot be the same; and n is an integer ranging from one through three. |
