ABSTRACT:
A liquid crystal display device comprises extended polymer networks formed in the liquid crystal cells. By adding a monomer and a photo-initiator into the liquid crystal material of a liquid crystal display, applying a bias voltage and exposing the display under a UV light, a polymer network can be formed. The polymer network modifies the electro-optical characteristic of a liquid crystal display device. With different bias voltages, polymer networks of different structures can be formed so that the color difference of the liquid crystal display with respect to red, green and blue light can be minimized. Liquid crystal display devices of fast switching response and low color dispersion can be fabricated.
