Light emitting device with light extraction layer and fabricating method thereof

摘要

A light emitting device with a light extraction layer and the fabricating method thereof are provided. Embedding a light extraction layer between an emitting layer and a packaging layer can reduce the difference in the refractive index between the emitting layer and the packaging layer. In addition, the refractive index of the light extraction layer is adjustable by doping various concentrations of metal materials in the light extraction layer. The mechanism helps improving the light emitting efficiency of the light emitting device.
