A reflection type semiconductor display device which can make satisfactory display even when external light is not satisfactorily intense is provided. A reflection type semiconductor display device according to the present invention can take in light other than incident light on a liquid crystal panel to be an auxiliary light source using optical fibers, and thus, display of high quality level can be made even indoors or in a place where light is faint. Further, by combining the semiconductor display device with a front light, insufficient amount of light can be supplemented with the front light.
