Abstract
A method of manufacturing an organic light-emitting device includes a heat treatment performed at a set or predetermined temperature range when forming a hole transport layer utilizing a solution process. When an emission layer is formed thereon utilizing a solution process, a mixed layer may be formed to a suitable thickness for improving hole injection into the emission layer. An organic light-emitting device may be manufactured utilizing the method.
