Abstract
Provided are an organic-light-emitting device and a display apparatus including the same. The organic light-emitting device includes: a first electrode; a second electrode facing the first electrode; and an organic layer between the first electrode and the second electrode and including at least one light-emitting unit, wherein the at least one light-emitting unit includes: an emission layer; and a hole transport region between the first electrode and the emission layer and including a first hole transport (HT) layer, the emission layer includes a host, the first HT layer includes a first compound, a minimum bond dissociation energy (BDE1HT) of the first compound is larger than a triplet energy (T1,host) of the host, and a minimum bond dissociation energy (BDEhost) of the host is larger than the triplet energy (T1,host) of the host.
