A liquid crystal display device includes a first transparent substrate having a plurality of electrodes, a second transparent substrate, a liquid crystal interposed between the first transparent substrate and the second transparent substrate, an illumination light source disposed on a back side of the first transparent substrate, pixel regions arranged in a matrix, and a reflecting film formed between the first transparent substrate and the electrodes. The reflecting film has at least one light transmission aperture in each pixel region and without slits at positions corresponding to gaps between adjacent ones of the pixel regions.
