Abstract
The present invention relates to a bistable polymer dispersed liquid crystal display comprising a support, at least one patterned first conductor layer having thereon at least one dried imaging layer comprising a substantial monolayer of isolated domains of liquid crystal material dispersed in a continuous polymer matrix, wherein said dried imaging layer further comprises at least one absorber colorant, and wherein said isolated domains have a size distribution such that the coefficient of variation (cv) is less than 0.35.
