摘要

The present specification relates to an organic electroluminescent device comprising: a first electrode; a second electrode; and an organic material layer provided between the first electrode and the second electrode, wherein the organic material layer comprises a light emitting layer and an electron transfer layer, the light emitting layer comprises a first host material, a second host material and a dopant material, the first host material has a HOMO energy level of ?5.9 eV or lower, and the second host material has a HOMO energy level higher than a HOMO energy level of the first host material by 0.1 eV to 0.2 eV.

說明書

R30 is selected from the group consisting of hydrogen; deuterium; a halogen group; a cyano group; a nitro group; a hydroxyl group; a substituted or unsubstituted alkyl group; a substituted or unsubstituted cycloalkyl group; a substituted or unsubstituted alkoxy group; a substituted or unsubstituted aryloxy group; a substituted or unsubstituted alkylthioxy group; a substituted or unsubstituted arylthioxy group; a substituted or unsubstituted alkylsulfoxy group; a substituted or unsubstituted arylsulfoxy group; a substituted or unsubstituted alkenyl group; a substituted or unsubstituted silyl group; a substituted or unsubstituted boron group; a substituted or unsubstituted alkylamine group; a substituted or unsubstituted aralkylamine group; a substituted or unsubstituted arylamine group; a substituted or unsubstituted heteroarylamine group; a substituted or unsubstituted aryl group; a substituted or unsubstituted fluorenyl group; a substituted or unsubstituted carbazole group; and a substituted or unsubstituted heteroaryl group, r30 is an integer of 1 to 3, and when r30 is 2 or greater, R10s are the same as or different from each other, and

the rest of the substituents have the same definitions as in Chemical Formula 2.

According to one embodiment of the present specification, R30 is hydrogen.

According to one embodiment of the present specification, Chemical Formula 5 may be represented by the following Chemical Formula 5-1.
