Abstract: An organic light emitting diode (OLED) and an organic light emitting device (e.g., a display device or a lighting device) comprising the OLED are described. An emissive layer includes a red emitting material layer, a yellow-green emitting material layer and a green emitting material layer disposed sequentially between two electrodes, where each of the emitting material layers has controlled thickness and includes at least one host with controlled energy level. The OLED and the organic light emitting device have improved pure color luminous efficiency and color gamut, as well as luminous efficiency and luminous lifespan.
