Abstract: Color distortion in Liquid Crystal Displays arises because, in addition to rotating the plane of polarization, liquid crystals are birefringent. This causes the emergent light to become elliptically polarized, the extent varying with wavelength, thereby upsetting the color balance. Prior art solutions to this involve use of a single birefringent layer to compensate for this. This approach is only partly successful. The present invention improves the color balance still further by providing a separate set of microcompensators for each primary color that comprises the display. By this means, an exact match between the color distortion introduced by the liquid crystal layer and the phase compensation needed to correct this can be made for each primary color separately. Several different arrangements of the micro color filters of the display and their corresponding microcompensators are shown and a cost effective method for manufacturing these structures is described.

Abstract: Prior art solutions to liquid crystal birefringence (which causes the emergent light to become elliptically polarized) have involved use of a single birefringent layer (macrocompensator) to compensate for this. This approach is only partly successful. The present invention improves the color balance still further by providing a separate set of microcompensators. Two of the color filters share a common microcompensator while a third color filter has its own microcompensator. The color filters are first formed on one of the two substrates' inner surfaces, with the appropriate microcompensators being then formed on the outward looking surface of the other substrate. By this means, a near perfect match between the color distortion introduced by the liquid crystal layer and the phase compensation needed to correct this can be made.

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.
