ABSTRACT:
In the preferred embodiment of the present invention, a ferroelectric LC layer is formed between first and second substrates of a LC panel. The LC panel is cooled at a low temperature, for example at −20° C., where the ferroelectric LC maintains a smetic phase. Due to the cooling, molecules are uniformly aligned for their early alignment state.
