• a first electrode and a second electrode facing each other, and
• an active layer between the first electrode and the second electrode,
• wherein the active layer includes a first compound represented by the following Chemical Formula 1:
• wherein
• R1 to R12 are independently hydrogen or a monovalent organic group,
• R1 to R12 are independently present or form a ring,
• L1 to L3 are independently a single bond or a divalent organic group, and
• R13 to R15 are independently a substituted or unsubstituted C1 to C30 alkyl group, a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C3 to C30 heterocyclic group, a substituted or unsubstituted C1 to C30 alkoxy group, a substituted or unsubstituted amine group, a substituted or unsubstituted C6 to C30 arylamine group, a substituted or unsubstituted silyl group, or a combination thereof.
