Organic light emitting diode and manufacturing method therefor

A method of manufacturing an organic light emitting diode, comprising:

• forming a lower electrode on a light-transmitting substrate;
• forming an organic thin film layer including an emission material layer on the lower electrode;
• forming a light-transmitting upper electrode on the organic thin film layer;
• forming a functional layer that enables mutual reinforcement and interference of transmitted light on the upper electrode;
• and
• forming a reflective layer on the functional layer,
• wherein the emission material layer includes an organic emission material comprised of a host and a dopant;
• and
• the host comprises at least one anthracene derivative represented by Formula 1A below:
• in Formula 1A, X1 to X10 are identical to or different from each other, and are each independently selected from among a hydrogen atom, a deuterium atom, a substituted or unsubstituted C1-C30 alkyl group, a substituted or unsubstituted C2-C30 alkenyl group, a substituted or unsubstituted C3-C30 cycloalkyl group, a substituted or unsubstituted C5-C30 cycloalkenyl group, a substituted or unsubstituted C1-C30 alkoxy group, a substituted or unsubstituted C6-C30 aryloxy group, a substituted or unsubstituted C1-C30 alkylthioxy group, a substituted or unsubstituted C5-C30 arylthioxy group, a substituted or unsubstituted C1-C30 alkylamine group, a substituted or unsubstituted C5-C30 arylamine group, a substituted or unsubstituted C5-C50 aryl group, a substituted or unsubstituted C3-C50 heteroaryl group containing O, N or S as a heteroatom, a substituted or unsubstituted silicon group, a substituted or unsubstituted boron group, a substituted or unsubstituted silane group, a carbonyl group, a phosphoryl group, an amino group, a nitrile group, a hydroxyl group, a nitro group, a halogen group, an amide group, and an ester group, and X1 and X10 are able to form an aliphatic, aromatic, aliphatic hetero, or aromatic hetero fused ring with an adjacent group.
