A light emitting device including a first electrode, a light emitting portion on the first electrode, the light emitting portion including a plurality of light emitting units and at least one interconnecting layer between ones of the light emitting units that are adjacent to each other, and a second electrode on the light emitting portion. The at least one interconnecting layer includes a p-type charge generation layer doped with a p-type dopant and an n-type charge generation layer doped with an n-type dopant. At least one of the p-type charge generation layer and the n-type charge generation layer has a concentration gradient of the p-type dopant or the n-type dopant.

Organic light emitting device

An organic light emitting diode (OLED) display includes a substrate, a thin film transistor disposed on the substrate, a first electrode disposed on the thin film transistor and electrically connected to the thin film transistor, a first auxiliary layer disposed on the first electrode, an emission layer disposed on the first auxiliary layer, an electron transport layer disposed on the emission layer, a first buffer layer disposed on the electron transport layer, and a second electrode disposed on the first buffer layer.

Organic light emitting diode display

An organic light-emitting display device includes a substrate which includes a plurality of areas, a plurality of first electrodes disposed on the areas of the substrate, respectively, a second electrode disposed on the first electrodes, and a plurality of emitting layers disposed between the first electrodes and the second electrode. At least two of the emitting layers are disposed on all of the areas.
