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.

Abstract: An organic light emitting diode (OLED) and an organic light emitting device comprising the OLED (e.g., a display device or a lighting device) are described. The OLED includes a plurality of emitting parts each of which can include an emitting material layer between two electrodes. Each of the emitting material layers is spaced apart from each other or from the electrodes. As the distances among the electrodes and the emitting material layers and/or among emitting material layers are controlled, the OLED can secure sufficient amount of light emission as well as beneficial luminous efficiency and wide viewing angle.
