Abstract
A light emitting device including a base, a first electrode, a barrier structure layer, a light emitting layer and a second electrode is provided. The barrier structure layer includes a first barrier layer in contact with the first electrode, a second barrier layer and a third barrier layer. The first barrier layer, the second barrier layer and the third barrier layer stack sequentially. The materials of the first barrier layer and the third barrier layer include a dielectric material. The material of the second barrier layer includes a metal material. A boundary between the third barrier layer and the second barrier layer keeps a vertical distance from the first electrode. The light emitting structure layer is disposed between the first electrode and the second electrode and surrounded by the barrier structure layer. The thickness of the light emitting structure layer is not greater than the vertical distance.
