| abstract | A liquid crystal layer 3 (figure 1a) exhibiting a cholesteric order is formed on an alignment film 2 on a substrate 1 by attaching active radiating cured liquid crystal composition and adjusting the alignment status of the liquid crystal composition by heating. Next, The liquid crystal layer 3 is irradiated with active radiation 4 of predetermined irradiation intensity transmitted through a photomask 10 (figure 1b), and the liquid crystal layer 3 is brought into contact with a solvent 5 (figure 1c), thereby removing the part 3b of the liquid crystal layer 3 not irradiated by active radiation 4 and retaining the part 3a irradiated by active radiation 4 so as to form a semi-cured cholesteric layer 3' having a predetermined pattern (figure 1d). Then, the semi-cured cholesteric layer 3' is irradiated with active radiation 6 to cure the semi-cured cholesteric layer 3' with a curing rate gradation from the base 9 side toward the surface opposite to the base 9, so that the selected reflection wavelength band of the semi-cured cholesteric layer 3' is widened (figure 1e). Lastly, by irradiating the semi-cured cholesteric layer 3' with active radiation 8, the semi-cured cholesteric layer 3' is cured while maintaining the cholesteric order in the widened band status, thereby forming a cured cholesteric layer 3"" (figure 1f). |
