Patent ID: 8404362

Claim:
An organic light-emitting element constituted by arranging a light-emitting layer between an anode and a cathode, wherein the light-emitting layer contains a polymer compound comprising a constitutional unit derived from an electron transport polymerizable compound represented by the following formula (1) and a constitutional unit derived from a phosphorescent polymerizable compound; wherein in formula (1), R 7 and R 14 are each independently an alkyl group having 1 to 12 carbon atoms or an alkoxy group having 1 to 12 carbon atoms, and R 1 to R 6 and R 8 to R 13 are hydrogen atoms, R 15 is a hydrogen atom or an alkyl group of 1 to 12 carbon atoms, and X 1 is a single bond or a group represented by any one of the following formulas (X11) to (X14): wherein R X11 is a single bond or an alkylene group of 1 to 12 carbon atoms, and R X12 is a single bond, an alkylene group of 1 to 12 carbon atoms or a phenylene group, and wherein the polymer compound further comprises a constitutional unit derived from a hole transport polymerizable compound represented by formula (8-3):
