A liquid crystal display device for producing a substantially uniform tone pattern by placing in the same display state all display dots producing the tone pattern which are associated with the same scanning electrode during each frame of a cycle. The method further includes adjusting the scanning waveform applied to each scanning electrode during each frame based on the tone pattern. Alternatively, the liquid crystal display device places all display dots which produce the tone pattern in the lit state for the same duration of time during the cycle and concurrently adjusts the scanning waveform applied to each scanning electrode during the cycle based on the tone pattern. Different groups of display dots which produce the tone pattern are placed in the non-lit display state at different portions of the cycle. Voltage disturbances giving rise to spikes and rounding of the voltage pulses occuring on the scanning and signal electrodes are substantially eliminated.
