摘要： A reflection-type liquid crystal display device, having a pair of substrates, at least one of which is transparent, a liquid crystal layer sandwiched between the pair of substrates, a light reflector section provided between the liquid crystal layer and one of the pair of substrates, and a polymeric medium layer with fine silver particles precipitated on the surface, as formed at the light reflector section. The reflection-type liquid crystal display is produced by the steps of: applying a mixture containing monovalent silver and a photosensitive polymeric medium; exposing the mixture to light, thereby photolithographically forming a light reflector layer of desired pattern; heating the light reflector layer under a predetermined temperature condition, thereby precipitating fine silver particles on the surface of the light reflector layer; and confronting a transparent substrate with the light reflector layer-formed substrate, and sandwiching a liquid crystal layer between the substrates.

摘要： A vinyl monomer is graft polymerized on an aromatic hydrocarbon-based polymer film substrate to introduce graft chains into the substrate and thereafter a functional monomer represented by the following formula and having sulfonic acid groups or functional groups capable of conversion to sulfonic acid groups is graft polymerized to introduce the sulfonic acid groups or the functional groups capable of conversion to sulfonic acid groups: where R is an aromatic ring or an aliphatic chain; X is (1) —OH, (2) —OLi, —ONa or —OK, (3) —F or —Cl, or (4) —OCnH2n+1 where n is an integer of 1 to 7. Since the graft chains obtained by graft polymerization of the vinyl monomer can also be utilized as scaffold polymers, the graft polymerizability of the functional monomer to the aromatic hydrocarbon-based polymer film substrate is sufficiently improved to enable the preparation of a polymer electrolyte membrane that excels not only in proton conductivity and mechanical strength but also in dimensional stability.
