摘要:
Provided is an organic light-emitting device which has an optical output with high emission efficiency and high luminance and which includes a pair of electrodes, and at least one layer including an organic compound and interposed between the electrodes, wherein the at least one layer including the organic compound includes an oligofluorene compound represented by the following general formula. At least a light-emitting layer of the at least one layer including the organic compound includes the oligofluorene compound and a light-emitting compound selected from a fluorescent compound and a phosphorescent compound. A weight ratio (B/A) of the light-emitting compound (B) selected from the fluorescent compound and the phosphorescent compound to the oligofluorene compound (A) is 1/100 or more and 100/100 or less.
