Patent ID: 8921843

Claim:
An organic light emitting device, comprising: a substrate comprising a first subpixel, a second subpixel, and a third subpixel; a plurality of first electrodes in the first subpixel, the second subpixel, and the third subpixel; a second electrode facing the first electrode; and an emission layer between the first electrode and the second electrode, the emission layer comprising: i) a first emission layer in the first subpixel for emitting a first color light in the first subpixel, ii) a second emission layer in the second subpixel for emitting a second color light in the second subpixel, and iii) a third emission layer in the first subpixel, the second subpixel and the third subpixel, for emitting a third color light in the third subpixel, the third emission layer comprising at least one compound represented by Formula 1: wherein, in Formula 1, R 1 to R 5 may be each independently selected from a hydrogen atom, a deuterium atom, a halogen atom, a hydroxyl group, a cyano group, a nitro group, a carboxyl group, a substituted or unsubstituted C 1 -C 60 alkyl group, a substituted or unsubstituted C 3 -C 60 cycloalkyl group, a substituted or unsubstituted C 1 -C 60 alkoxy group, a substituted or unsubstituted C 6 -C 60 aryl group, a substituted or unsubstituted C 2 -C 60 heteroaryl group, a substituted or unsubstituted C 6 -C 60 aryloxy group or a substituted or unsubstituted C 6 -C 60 arylthio group; a1 and a2 are each independently an integer of 0 to 4; b1 and b2 are each independently an integer of 0 to 4; a1+b1 is 4; a2+b2 is 4; c1 and c2 are each independently an integer of 0 to 9; and b1 and b2 are not both 0.
