Patent ID: 8212280

Claim:
A light-emitting device which has a pixel region having a light-emitting element, the light-emitting element comprising: a reflective electrode over a substrate; an electroluminescent layer over the reflective electrode, the electroluminescent layer comprising an organic compound; a transparent electrode over the electroluminescent layer; a first layer over the transparent electrode, the first layer comprising a material selected from silicon nitride, silicon oxide, silicon nitride oxide, and silicon oxynitride; and a second layer over the first layer, the second layer comprising an inorganic material, wherein the first layer has a stacked structure comprising a third layer and a fourth layer, wherein the third layer comprises a material selected from silicon nitride, silicon oxide, silicon nitride oxide, and silicon oxynitride, and wherein the fourth layer comprises a material selected from silicon nitride, silicon oxide, silicon nitride oxide, and silicon oxynitride.
