Abstract: An organic light-emitting display device characterized by improved reliability is disclosed. The organic light-emitting display device is configured such that each of an organic encapsulation layer, which is disposed on a light-emitting element, and an upper inorganic encapsulation layer, which is disposed on the organic encapsulation layer, are divided into a plurality of parts. Even when cracks are formed in a subpixel due to an external impact or when external moisture or oxygen permeates into the subpixel, therefore, it is possible to prevent the cracks, the moisture, or the oxygen from diffusing to an adjacent subpixel, whereby the reliability and lifespan of the display device are improved.

Abstract: A quantum dot includes a seed and a core enclosing the seed. The core is grown from the seed to improve size uniformity of the core. The seed includes a first compound without Cd. The first compound may be GaP. The core may include a second compound including elements from group XIII and group XV. The second compound may be InP. The quantum dot may also include a first shell of a third compound enclosing the core. The third compound may be ZnSe or ZnS. The quantum dot may also include a second shell of a fourth compound enclosing the first shell. The fourth compound may be ZnS when the third compound is ZnSe. Embodiments also relate to a quantum dot including first to third elements selected from XIII group elements and XV group elements and fourth to sixth elements selected from XII group elements and XVI group elements.
