Organic light-emitting device

An apparatus comprising:

• an opaque substrate;
• an organic light-emitting device;
• and
• a color filter,
• wherein the organic light-emitting device comprises:
• a pair of electrodes including an anode and a cathode;
• and
• a layer comprising an organic compound disposed between the pair of electrodes,
• wherein the layer comprises a first compound represented by the general formula (I):
• wherein R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13, R14, R15, and R16 each represent, independently of one another, a hydrogen atom, an alkyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, a substituted amino group, or a halogen atom;
• and
• a second compound with a pyrene skeleton or a fluorene skeleton having an energy gap larger than an energy gap of the first compound, and
• wherein each of the combinations of R1 and R9, R2 and R10, R3 and R11, R4 and R12, R5 and R13, R6 and R14, R7 and R15, and R8 and R16 is a combination of the same substituents.
