Abstract: It is an object of the present invention to provide a high-contrast light-emitting device without using a polarization plate. In particular, it is an object of the present invention to make contrast control simpler for a light-emitting device provided with a color filter.A light-emitting device according to the present invention has a feature of having a structure for reducing reflection of light from a light-emitting later at a reflective electrode, and further, has a feature of absorbing wavelengths other than the light by a color filter to enhance the contrast. Accordingly, contrast control can be performed in consideration of only a luminescence component from the light-emitting layer, and is thus made simpler.
