| Zusammenfassung: | According to the present invention, provided are an organic light emitting diode including: a light emitting material layer including first to third layers; a positive electrode located at one side of the light emitting material layer; and a negative electrode disposed on the other side of the light emitting material layer to face the positive electrode. The first layer includes a TADF dopant, the second layer includes a first fluorescent dopant, and the third layer includes a TTA dopant. The present invention also provides an organic light emitting display device including the organic light emitting diode. Therefore, an objective of the present invention is to solve a problem of low lighting efficiency and color purity in a conventional light emitting material.
