Abstract

A condensed cyclic compound is represented by Formula 1, and an organic light-emitting diode includes the condensed cyclic compound:

wherein, in Formula 1, the descriptions of Ar 1 to Ar 4 , and R 1 to R 6 are as defined in the present specification. An organic light-emitting diode including an organic layer including the condensed cyclic compound may have a low driving voltage, a high light-emitting efficiency, and a long lifespan.
