| titleOfInvention | Manufacturing method of optical anisotropy layer |
| abstract | A manufacturing method of the present invention is provided to manufacture an optical anisotropy layer formed by a liquid crystal composition containing a polymer liquid crystal compound and including a plurality of optical anisotropy areas, each having a delayed phase axis direction different from the others. The manufacturing method includes: (1) an optical alignment polymer layer formation step for coating an optical alignment polymer on a substrate; (2) a first illumination step for illuminating a first polarized light to the optical alignment polymer layer through a photo mask when the following necessary condition A and necessary condition B are satisfied; (3) a second illumination step for illuminating a second polarized light with a vibration direction different from that of the first polarized direction to the optical alignment polymer layer without passing through the photo mask after the first polarized light illuminates, so as to form a patterned alignment film; (4) a coating step for coating the liquid crystal composition on the patterned alignment film so as to form a coating film; (5) an alignment step for allowing the coating film to be kept in a temperature in which the liquid crystal component contained in the coating film is in a liquid crystal state, so as to form an aligned film of liquid crystal component; (6) a polymerization step for polymerizing the polymer liquid crystal compound contained in the aligned film of the liquid crystal component. The necessary condition A is such that a light absorbing degree of the optical alignment polymer layer in the area illuminated by the first polarized light satisfies expression (I): A (b)/A (a) ≤ 0.95, wherein A (a) represents the light absorbing degree at a wavelength of 314 nm before the first polarized light illuminates, and A (b) represents the light absorbing degree at a wavelength of 314 nm after the first polarized light illuminates. The necessary condition B is such that a double refractive index of the optical alignment polymer layer in the area illuminated by the first polarized light satisfies expression (ii): <DELTA>n(550)≥ 0.005, wherein <DELTA>n(550) represents the double refractive index at a wavelength of 550 nm. |
