1. A liquid crystal display device comprising:

  • a plurality of light sources emitting a plurality of lights; and

    a pixel portion, the pixel portion comprising;

    a first pixel electrode having a light-transmitting property; and

    a second pixel electrode which is a reflective electrode and placed adjacently to the first pixel electrode,wherein the first pixel electrode is electrically connected to a first transistor and the second pixel electrode is electrically connected to a second transistor,wherein the pixel portion is divided into a plurality of regions,wherein color display is performed by controlling the plurality of lights whose hues are different per the plurality of regions and applying a voltage to a first region of the liquid crystal layer overlapping with the first pixel electrode, andwherein a still image is displayed by driving the second transistor in a period when the plurality of light sources are turned off and applying a voltage to a second region of the liquid crystal layer overlapping with the second pixel electrode.
