There is provided an organic light emitting device including: an anode, a cathode, and layer containing an organic compound, the layer being interposed between the anode and the cathode, in which the layer containing an organic compound contains at least one kind of the oligofluorene compound represented by the following general formula (I): wherein: R<SUB>1 </SUB>and R<SUB>2 </SUB>each represent an alkyl group, and may be identical to or different from each other, and R<SUB>1</SUB>'s and R<SUB>2</SUB>'s by which different fluorene rings are substituted may be identical to or different from each other, provided that at least four substituents of all substituents each represented by R<SUB>1 </SUB>or R<SUB>2 </SUB>are each an alkyl group having 4 or more carbon atoms, and at least four substituents of all the substituents are each an alkyl group having 1 or 2 carbon atoms; and n represents an integer of 4 to 10.
