ABSTRACT:
A method of matrix-driving liquid crystal which exhibits a cholesteric phase and a liquid crystal display apparatus which is driven by the method. The method comprises a reset step Trs, a selection step Ts, an evolution step Trt and a display step Ti, and the selection step comprises a selection pulse application step Tsp, and a pre-selection step Tsz and a post-selection step Tsz′ respectively before and after the selection pulse application step Tsp. The ratio of the length of the selection pulse application step Tsp to the length of the selection step Ts is changed with changes in temperature, and thereby, the temperature dependency of the responsibility of liquid crystal is compensated.
