Abstract: A light emitting device includes a first electrode, a second electrode, an organic layer and a conductive layer. The organic layer is disposed between the first electrode and the second electrode. The conductive layer is disposed between the organic layer and the first electrode. A refractive index of the conductive layer is lower than a refractive index of the organic layer in a visible light wavelength, so that an energy radiated by a light emitted by the organic layer through the first electrode is less than an energy radiated by the light emitted by the organic layer through the second electrode.
