Abstract. In order to select proper cholesteric liquid crystal (ChLC) materials and drive schemes for cholesteric liquid crystal displays (ChLCD), it is necessary to make the protracted experimental analysis of electro-optical hysteresis properties of ChLCs. Method for approximation of electro-optical characteristics of ChLC offered in this article significantly decreases duration of experimental analysis above. Accuracy of this method is estimated by the comparison of volt-brightness and volt-contrast characteristics of ChLC obtained both by experimental measuring and proposed method of approximation.

Keywords: cholesteric liquid crystal, liquid crystal display.
