Abstract
A color polymer dispersed liquid crystal display includes a lower substrate, an upper substrate, color liquid crystal-polymer films, and two transparent liquid crystal driving electrodes, among others. The color liquid crystal-polymer films are formed by foaming polymer films mixed with red, green and blue pigments to form porous films of red, green, and blue colors and then dropping and injecting liquid crystal into droplets of the porous films under vacuum condition. One of the two transparent liquid crystal driving electrodes is disposed between the lower substrate and the PDLC films, and the other is disposed between the PDLC films and the upper substrate. The changes in properties of the PDLC films, which may be caused by unstable phase separation in a conventional phase separation process, are reduced, and the colors are improved.
