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.

Abstract
A display control unit is combined with a display device including scanning and signal electrodes and a display element sandwiched between the scanning and signal electrodes and includes a key or the like for setting drive waveforms for driving the scanning and/or signal electrodes prior to drive timings of the scanning and signal electrodes. In the display device, a ratio of a voltage applied to an intersection between a selected scanning line and a selected information signal line to a voltage applied to an intersection between a non-selected scanning line and a selected information signal line is variably changed in accordance with a temperature change.
