[0179] (Measurement of Refractive Index)
[0180] A photo-orienting polymer (PA-1, photo-isomerizing polymer) was dissolved in cyclohexanone to prepare a 30 wt. % solution. The solution was applied onto a plate of high refractive glass, dried and exposed to linearly polarized light (200 mW / cm.sup.2) at 435 nm for 10 seconds at room temperature. The refractive index of the, thus-formed film of photo-orienting polymer (optically anisotropic phase) was measured by means of an Abbe's refractometer, and thereby found 1.54 (ne) and 1.62 (n0) in the directions parallel and perpendicular to the polarizing direction, respectively.
[0181] (Production of Light-scattering Polarizing Element)
[0182] In 90 weight parts of water, 10 weight parts of gelatin was added and heated to dissolve. To the obtained solution, 2 weight parts of 30 wt. % cyclohexanone solution of photo-orienting polymer (PA-1, photo-isomerizing polymer) was added and emulsified by means of a homogenizer.

[0187] (Measurement of Refractive Index)
[0188] A photo-orienting polymer (PA-5, photo-dimerizing polymer) in the amount of 10 weight parts and a rod-like liquid crystal compound (N26) in the amount of 90 weight parts were mixed. The mixture was dissolved in dichloromethane to prepare a 30 wt. % solution. The solution was applied onto a plate of high refractive glass, dried, exposed to linearly polarized light (200 mW / cm.sup.2) at 365 nm for 10 seconds at room temperature, and then further exposed to non-polarized light (200 mW / cm.sup.2) at 310 nm for 10 seconds so that the molecules of the rod-like liquid crystal compound might be polymerized to fix the alignment. The refractive index of the thus-formed film (optically anisotropic phase) was measured by means of an Abbe's refractometer, and thereby found 1.66 (ne) and 1.54 (n0) in the directions parallel and perpendicular to the polarizing direction, respectively.

[0195] (Measurement of Refractive Index)
[0196] A photo-orienting polymer (PA-1, photo-isomerizing polymer) in the amount of 10 weight parts and a rod-like liquid crystal compound (N26) in the amount of 90 weight parts were mixed. The mixture was dissolved in cyclohexanone to prepare a 30 wt. % solution. The solution was applied onto a plate of high refractive glass, dried, exposed to linearly polarized light (200 mW / cm.sup.2) at 435 nm for 10 seconds at room temperature, heated at 130.degree. C. for 30 minutes, and then further exposed to non-polarized light (200 mW / cm.sup.2) at 310 nm for 10 seconds so that the molecules of the rod-like liquid crystal compound might be polymerized to fix the alignment. The refractive index of the thus-formed film (optically anisotropic phase) was measured by means of an Abbe's refractometer, and thereby found 1.54 (ne) and 1.65 (n0) in the directions parallel and perpendicular to the polarizing direction, respectively.
