1. A liquid crystal display device comprising:

  • scanning and information signal lines;

    a liquid crystal element comprising a ferroelectric liquid crystal sandwiched between said scanning and information signal lines;

    means for sequentially selecting said scanning lines and applying an information signal to said information signal lines in synchronism with an application of a scanning signal to said selected scanning line;

    memory means for storing applied voltage data adapted to apply voltage to an intersection of a scanning line and a signal line in accordance with a temperature change; and

    control means operating in accordance with a temperature change, for varying a ratio of a voltage applied to an intersection of a non-selected scanning line and a selected information signal line to a voltage applied to an intersection of a selected scanning line and a selected information signal line in accordance with the applied voltage data stored in said memory means after display-driving the last scanning line in an effective display area of the device formed by said scanning and information lines, but before display-driving the first scanning line in the effective display area.
