Abstract
A reduced driving voltage polymer dispersed liquid crystal display (10) has a transparent polymer matrix (20) disposed between two substrates (12, 14). Droplets of a nematic liquid crystal fluid (22) are uniformly dispersed throughout the polymer matrix. Particles of an optically transparent material (24) that is a weak conductor are uniformly dispersed throughout the polymer matrix to reduce the electrical potential across the polymer. The enhanced conductivity of the polymer matrix allows the display to be operated at a reduced voltage.
