摘要：
A quantum dot includes a core and a plurality of shell layers surrounding the core. The core has a band gap less than that of the outermost shell layer, and the outermost shell layer has a band gap less than that of a second shell layer. Thus, a light emitting device including the quantum dot according to an embodiment may have an improved lifespan of the device and excellent luminous efficiency characteristics.
