ABSTRACT:
To uniform the liquid crystal particle of the liquid crystal layer of a PDLCD where a liquid crystal is scattered and emulsified with a polymer, the polymer is scattered on a conductive layer of a substrate. The liquid crystal is scattered thereon to be emulsified during a predetermined hour. Thereafter, by the same method as that of forming the polymer layer, the polymer is scattered on the liquid crystal layer to form a second polymer layer thereby obtaining the homogeneous thickness of the liquid crystal layer of the PDLCD.
