ABSTRACT:
It is an object of the present invention to provide a light emitting device which can be made into a module with smaller volume. By using a light emitting element represented by an EL element and the like as a pixel portion, two pixel portions are formed at different portions over the light emitting device. A first pixel portion comprises a plurality of pixels arranged in matrix. In the periphery of the first pixel portion, a first source line driving circuit and a first gate line driving circuit for transmitting signals to the first pixel portion are formed. A second pixel portion is formed of passive pixels, and segregated from a TFT group which constitutes the first pixel portion, the first source line driving circuit, and the first gate line driving circuit in the direction from the back surface of the substrate to the top surface of the substrate by interposing an interlayer film therebetween.
