Method for photographically producing multi-colour filter arrays for use in LCD

摘要

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 the steps of : (i) exposing a silver halide colour photographic (print) material comprising a plurality of differently spectrally sensitive silver halide emulsion layers on a glass support, with a single step multicolour pixelwise exposure, (ii) colour processing said exposed print material producing thereby in each silver halide emulsion layer a differently coloured pixel pattern, (iii) coating said colour processed print material at its silver halide emulsion layer assemblage side with a hydrophobic water-impermeable organic resin layer (iv) curing said organic resin layer by heating said layer at temperatures between 100 DEG C and 250 DEG C and (v) depositing an transparent electrode layer on said organic resin layer, characterised in that in the colour processing a developer solution is used comprising a N,N-disubstituted p-phenylene diamine derivative in which the disubstituted amine group carries a -CHR<1>R<2> group.
