Abstract:
Disclosed is a display device including a pixel portion having a plurality of pixels which have a display element and a transmissive portion. The display element includes a light-emitting element which does not transmit external light, while the transmissive portion is arranged to transmit external light. In the display element, a top-emission or bottom-emission type light-emitting element is provided. On the other hand, no light-emitting element or a dual-emission type light-emitting element which possesses an EL layer interposed between two light-transmissive electrodes is provided to the transmissive portion. The emission color of the display element is controlled by a color filter which overlaps with the light-emitting element in the display element, while no color filter is given to the transmissive portion.
