摘要：
Discussed is an organic light emitting device in which a light emitting layer includes a host and different kinds of dopants, the fluorescent dopant is formed of a material having energy level properties facilitating thermally activated delayed fluorescence (TADF), and thus energy is concentratedly transferred to the fluorescent dopant so as to increase luminous efficacy of a single color.
