1. An anthracene derivative represented by the following Chemical Formula A-1:
 wherein,
R1 to R5, which are same or different, are each independently a hydrogen or deuterium atom,
R is a deuterium atom,
n is an integer of 0 to 8, with a hydrogen atom positioned on an aromatic carbon atom which is not substituted with R within the anthracene moiety,
L1, which functions as a linker, is a single bond or a deuterium-substituted or unsubstituted arylene of 6 to 12 carbon atoms;
R12 to R14, which are same or different, are each independently a hydrogen or deuterium atom, and
R15 to R18, which are same or different, are each independently selected from a hydrogen atom, a deuterium atom, a deuterium-substituted or unsubstituted phenyl, a deuterium-substituted or unsubstituted biphenyl, a deuterium-substituted or unsubstituted terphenyl, a deuterium-substituted or unsubstituted naphthyl, a deuterium-substituted or unsubstituted phenanthryl, and a fluorenyl in which identical or different alkyls of 1 to 5 carbon atoms can or cannot be substituted on the carbon atom at position 9 and a deuterium atom can or cannot be substituted on each of the carbon atoms of the aromatic rings,
at least one of R15 to R18 being selected from a deuterium-substituted or unsubstituted phenyl, a deuterium-substituted or unsubstituted biphenyl, a deuterium-substituted or unsubstituted terphenyl, a deuterium-substituted or unsubstituted naphthyl, a deuterium-substituted or unsubstituted phenanthryl, and a fluorenyl in which identical or different alkyls of 1 to 5 carbon atoms can or cannot be substituted on the carbon atom at position 9 and a deuterium atom can or cannot be substituted on each of the carbon atoms of the aromatic rings,
wherein the anthracene derivative has a degree of deuteration of 30% or more (percentages of all deuterium atoms bonded directly to carbon atoms of the anthracene derivative relative to a sum of all deuterium and hydrogen atoms bonded directly to carbon atoms of the anthracene derivative).
