Abstract
A light-emitting device includes a heterocyclic compound represented by Formula 1: The heterocyclic compound represented by Formula 1 may have a high glass transition temperature (T) and/or melting point for excellent thermal resistance, and excellent hole injectability and/or transportability. Accordingly, the light-emitting device may have excellent luminance, luminescence efficiency, lifespan, and/or driving voltage.
