Abstract
Provided are an organic light-emitting device including an arylamine-based compound including a thermally decomposable group, and an arylamine-based compound including a thermally decomposable group. The organic light-emitting device includes: a first electrode; a second electrode facing a first electrode; and an organic layer between the first electrode and the second electrode and including an emission layer, the organic layer including an arylamine-based compound in which the thermally decomposable group has been thermally decomposed and removed from the arylamine-based compound including the thermally decomposable group.
