An object of the present invention is to provide a light emitting device including an organic light emitting layer and an organic compound and having high light emitting efficient along with less deterioration in characteristics. In the light emitting device, an anode, a cathode facing the anode, light emitting layers each comprising an organic compound and being provided between the anode and the cathode, and carrier transporting layers each comprising an organic compound, are provided over a substrate. Each of the light emitting layers and each of the carrier transporting layers are alternately stacked. A thickness of each of the carrier transporting layers is thinner than that of each of the light emitting layers. When each of the carrier transporting layers is a hole transporting layer, each of the light emitting layers has an electron transporting property. When each of the carrier transporting layers is an electron transporting layer, each of the light emitting layers has a hole transporting property.
