<p>A liquid crystal display device is provided to realize a tone display. The liquid crystal display is arranged to have a display panel (1) having a plurality of pixels ranged in a matrix manner. Those pixels are formed of a pair of transparent electrodes (5,6) and a liquid crystal layer (4) filled therebetween. A scan voltage (VS) is applied to one transparent electrode (5) for specifying a pixel row. A signal voltage (VD) is applied to the other transparent electrode (6) for defining luminous or non-luminous sections of each pixel. A bias electrode (7) is provided on at least one side of each pixel. Further, a bias voltage (Vb) applying unit is also provided to apply a bias voltage (Vb) for a tone display for adjusting an electric-field gradient along the pixel width onto the bias electrode (7) in synchronous with the application of the signal voltage (VD) onto the other transparent electrode. <IMAGE></p> |
