Abstract:
A method of fabricating polymer networks for an LCD device having a plurality of pixels formed by a pair of substrates facing each other with a space in which a liquid crystal material is filled, each of said plurality of pixels including red, green and blue sub-pixels, comprising the steps of: mixing a monomer and a photo-initiator into said liquid crystal material;forming a first polymer network within said space by applying a first bias voltage to said plurality of pixels while using a first mask for exposing said red sub-pixels under a UV light for a pre-determined period of time;forming a second polymer network within said space by applying a second bias voltage to said plurality of pixels while using a second mask for exposing said green sub-pixels under a UV light for a pre-determined period of time; andforming a third polymer network within said space by applying a third bias voltage to said plurality of pixels while using a third mask for exposing said blue sub-pixels under a UV light for a pre-determined period of time;wherein said first, second and third bias voltages are selected for forming said first, second and third polymer networks with different structures for minimizing the difference in phase retardation introduced by said liquid crystal material with respect to red, green and blue light for reducing the color dispersion of said liquid crystal display device.
