ABSTRACT:
A photographic print material suited for the production of a multicolor filter array element for use in a liquid crystal display device including a liquid crystal layer wherein the print material comprises a glass plate supporting on one side thereof (i) a silver halide emulsion layer sensitive to blue light and containing a yellow dye forming color coupler, (ii) a silver halide emulsion layer sensitive to green light and containing a magenta dye forming color coupler, and (iii) a sliver halide emulsion layer sensitive to red light and containing a cyan dye forming color coupler. The red light sensitive emulsion layer is disposed on the side of the array remote from the glass supporting plate and in each of the silver halide emulsion layers the equivalent ratio of silver halide to color coupler is at least 1 and preferably 1.2. A water-impermeable organic resin covering layer is applied over the red light sensitive emulsion layer and a transparent electrode layer is vacuum deposited over the covering layer. In the liquid crystal display device, the filter array element is arranged with its glass plate opposite from the liquid crystal layer.
