Abstract

A method is provided for manufacturing a multicolour filter array element, firmly associated with a transparent electrode layer in a multicolour liquid crystal display device, comprising a silver halide colour photographic material wherein the colour processing of the silver halide colour material comprises a treatment of the colour processed colour material in a solution comprising at least one group III metal ion. The processing method diminishes the yellowing, due to heating, of the processed photographic silver halide colour material.
