Abstract
Syrup in which photo-curable resins and liquid crystals are compound is injected into a liquid crystal cell, and then ultraviolet rays are radiated to the liquid crystal cell to harden the photo-curable resins through photo polymerization. In this case, a material for fluorescing by ultraviolet rays is added to the syrup.
Claims8
A polymer dispersed liquid crystal device comprising:
- a liquid crystal cell in which the circumference of a pair of substrates is sealed by a sealant;
- and
- a polymer dispersed liquid crystal layer that includes photo-curable resins and liquid crystals, and is provided between the pair of substrates of the liquid crystal cell, the photo-curable resins and liquid crystals being polymerized and hardened by a light component having a first wavelength,
- wherein the polymer dispersed liquid crystal layer contains a material for fluorescing by a light component having a second wavelength.

A method of manufacturing a polymer dispersed liquid crystal device, comprising steps of:
- radiating a light component having a first wavelength to a liquid crystal cell in which a mixed liquor of liquid crystals and non-hardened photo-curable resins is injected between a pair of substrates;
- and
- forming a polymer dispersed liquid crystal layer, which includes hardened photo-curable resins and the liquid crystals, by hardening the photo-curable resins through photo polymerization,
- wherein the mixed liquor contains a material for fluorescing by a light component having a second wavelength.
