Abstract
Provided is a light-emitting device including: a first electrode; a second electrode facing the first electrode; and an interlayer between the first electrode and the second electrode and including an emission layer. The emission layer includes: a first emission layer including a first host; and a second emission layer including a second host, wherein a triplet energy (T1H1) of the first host and a triplet energy (T1H2) of the second host satisfy Equation (1): T1H1−T1H2≥0.2 eV (1).
