Abstract:
A display device including a first substrate including a plurality of reflection electrodes on a front side of the first substrate, the plurality of reflection electrodes including a first reflection electrode and a second reflection electrode which is farther away from a light source than the first reflection electrode; a second substrate including a transparent electrode on a back side of the second substrate; a light modulation layer which includes a polymer dispersed liquid crystal layer containing a liquid crystalline monomer and liquid crystal molecules dispersed in the liquid crystalline monomer, the light modulation layer being disposed between the plurality of reflection electrodes and the transparent electrode; a drive section driving the plurality of reflection electrodes and the transparent electrode, wherein an application time of a first drive voltage applied between the transparent electrode and the first reflection electrode is shorter than an application time of a second drive voltage applied between the transparent electrode and the second reflection electrode.
