• wherein, in Chemical Formula 1,
• R1 to R5 are independently hydrogen, a deuterium, a substituted or unsubstituted C1 to C4 alkyl group, or a phenyl group,
• Z1 to Z3 are independently CRa or N,
• at least two of Z1 to Z3 are N,
• Ra and R6 are hydrogen, a deuterium, a substituted or unsubstituted C1 to C10 alkyl group, or a substituted or unsubstituted C6 to C12 aryl group,
• Ar1 and Ar2 are independently hydrogen, a deuterium, a substituted or unsubstituted C1 to C10 alkyl group, or a substituted or unsubstituted C6 to C18 aryl group,
• a, b, c, d, and e are independently an integer of 0 or 1,
• 4≤a+b+c+d+e≤5, and
• the “substituted” refers to replacement of at least one hydrogen by deuterium, a C1 to C4 alkyl group, or a C6 to C12 aryl group.
