ABSTRACT:
A light emitting device includes a light emitting member formed on a substrate, a first blocking layer formed on the light emitting member and an absorbing layer interposed between the light emitting member or the first blocking layer. The first blocking layer prevents oxygen or moisture in air from permeating into the light emitting member generating light. The absorbing layer absorbs the oxygen or the moisture that passes through the first blocking layer. The light emitting device may have reduced volume and improved lifetime.
