In order to utilize the LCoS, this paper advances a new patten liquid material which is ferroelectric liquid crystal. It has
the characteristics, such as time division-style full-color display, high resolution, low voltage and high speed response. If
it is used in the microdisplay, we can attain large area visual display, high open rate and high responding time. The
alignment of ferroelectric liquid crystal is very complicated, so we use photo-alignment, rubbing or hybrid-alignment to
determine the direction of liquid. Once the liquid layer has been fabricated, we use space parameter method to analyse
the liquid layer, and we make sure the detailed optical thickness and pretilted angle.
