1. A liquid crystal display device, comprising:

  • a pair of oppositely disposed substrates each having a plurality of opposing electrodes, and a ferroelectric liquid crystal disposed between the substrates so as to form a plurality of pixels each composed by a combination of a pair of the opposing electrodes and the ferroelectric liquid crystal disposed therebetween;

    wherein each pixel is provided with regions of different polarity inversion threshold voltages, and at least one of said pair of opposing electrodes is provided with a plurality of regions having island-shaped unevennesses at different densities including a region with a higher density of unevennesses corresponding to a region of a lower polarity inversion threshold voltage and a region with a lower density of unevennesses corresponding to a region of a higher polarity inversion threshold voltage.
