Abstract

A compound represented by Formula 1, and an organic light-emitting device including the compound: In Formula 1, when Land/or Lis a phenyl group, a pyridyl group, a pyrimidyl group, and/or a 1,3,5-triazinyl group having binding sites that are ortho- or meta- to each other, and the compound of Formula 1 is included the second hole transport layer (HTL2), the efficiency and luminance half-life of a device may increase due to the HTL2 having a higher T(e.g., triplet) energy level compared to examples in the related art using a para-substituted phenyl linker.
