を駆動できるので彩度はより鮮明なものとなる。Therefore, since the transmitted light is transmitted through the coloring member 214 only once, a transmissive color corresponding to the color density of the coloring member 214 can be obtained. At this time, the saturation of the reflected light is reduced because the reflected light component that does not pass through the coloring member 214 is included, so that the saturation of the transmissive display is relatively increased. Further, since the liquid crystal can be driven only by the dots 222 to which the signal is supplied as described above, the saturation becomes clearer.

を駆動できるので彩度はより鮮明なものとなる。Therefore, since the transmitted light is transmitted through the coloring member 314 only once, a transmissive color corresponding to the color density of the coloring member 314 can be obtained. At this time, the saturation of the reflected light is reduced because the reflected light component that does not pass through the coloring member 314 is included, so that the saturation of the transmissive display is relatively increased. Further, since the liquid crystal can be driven only by the dots 322 to which the signal is supplied as described above, the saturation becomes clearer.
