Organic light-emitting diode having long lifespan, low voltage, and high efficiency property

An organic light-emitting diode, comprising:

• a first electrode;
• a second electrode facing the first electrode;
• and a light-emitting layer intercalated between the first electrode and the second electrode,
• wherein the light-emitting layer comprises at least one of the amine compounds represented by the following Chemical Formula A and at least one of the anthracene compounds represented by the following Chemical Formula B:
• wherein,
• Z3 is a substituted or unsubstituted aromatic hydrocarbon ring, selected from between Structural Formula 11 and Structural Formula 15:
• wherein
• “-*” denotes a bonding site for forming a 5-membered ring containing the carbon atom connected to both R14 and R15,
• R's are as defined below for R16 to R19, and
• m is an integer of 1 to 8 wherein when m is 2 or more or when R is two or more, individual R's are same or different,
• the substituents R14 and R15, which are the same or different, are each independently one selected from among a substituted or unsubstituted alkyl of 1 to 30 carbon atoms, and a substituted or unsubstituted aryl of 6 to 50 carbon atoms,
• R16 to R19, which are the same or different, are each independently one selected from among a hydrogen atom, a deuterium atom, with a proviso that one of the substituents R16 to R19 represents a single bond attached to the linker L in a Q moiety,
• two adjacent carbon atoms within Z3 form a five-membered ring with the carbon atom having both the substituents R14 and R15 thereon, thus establishing a fused ring,
• a carbon atom of the aromatic ring of Z3 which does not participate in forming the five-membered ring is bonded to the linker L in a Q moiety,
• the linker L represents a single bond,
• n is an integer of 1,
• the respective moieties Q's which are bonded to Z3 and to one of R16 to R19 are same or different,
• the substituents Ar1 and Ar2, which are same or different, are each independently one selected from among a substituted or unsubstituted aryl of 6 to 40 carbon atoms and a substituted or unsubstituted heteroaryl of 2 to 30 carbon atoms;
• wherein,
• R21 to R28, which are same or different, are each independently one selected from among a hydrogen atom, and a deuterium atom,
• R31 to R37, which are same or different, are each independently one selected from among a hydrogen atom, a deuterium atom, a substituted or unsubstituted aryl of 6 to 50 carbon atoms, and
• the substituent Ar3 is a deuterium substituted or unsubstituted naphthyl or a substituent represented by the following Structural Formula C:
• wherein R41 to R45 are same or different and are a hydrogen atom, a deuterium atom, or a deuterium substituted or unsubstituted aryl of 6 to 50 carbon atoms, or a deuterium substituted or unsubstituted alkyl of 1 to 30 carbon atoms,
• wherein the term ‘substituted’ in the expression ‘substituted or unsubstituted’ means having at least one substituent selected from the group consisting of a deuterium, a halogen, an alkyl of 1 to 24 carbon atoms, a halogenated alkyl of 1 to 24 carbon atoms, an aryl of 6 to 24 carbon atoms and an alkylsilyl of 1 to 24 carbon atoms.
