<p>PURPOSE:To enable to prepare a large size element of a ferrodielectric liquid crystal having a memory storage property, especially, a matrix element by forming a spacer from a polyimide type org. high polymer substance. CONSTITUTION:The polyimide type org. high polymer is used to the spacer 1. When the voltage is applied to both ends of the low resistance electrode 3 of the title element, the electric current flows. As the high resistance electrode 2 contacts with the low resistance electrode 3, the electric current flows to both electrodes, thereby generating Joule heat. The heating value coming from the low resistance electrode 3 is larger than that of the electrode 2. Therefore, the temperature distribution having a peak at the position of the low resistance electrode 3 in the vertical direction against the electrode, is obtd. The mono- domain of the smectic phase may grow from the interface between the liquid crystal and the spacer by slowly reducing the surrounding temp. maintaining the electric current to the constant, or by dropping the value of the electric current maintaining the surrounding temp. to the constant, or by lowering both the surrounding temp. and the value of the electric current.</p> |
