ABSTRACT:
In a liquid-crystal display device, one of substrates has pixel electrodes and TFTs for driving the pixel electrodes, and the other substrate has opposing electrodes formed thereon. The orientation of the liquid crystal is controlled to exhibit bistability in which bistable states having different transmittances are maintained when no voltage is applied as a result of applying a voltage exceeding a threshold value, and to exhibit a continuous response characteristic in response to an applied voltage in a predetermined range which does not exceed the threshold value. The voltage applied to the liquid crystal can be selectively controlled between a voltage equal to or higher than the threshold value and a voltage lower than the threshold value, and a two-gradation display using the bistability and a multi-gradation display using the response characteristic are made.
