| titleOfInvention | Birefringent film and method for producing the same |
| abstract | (57) [Abstract] [Object] A birefringent film (optical compensation film) having a tilted optical axis prepared by polarizing exposure of a laminated photoreactive polymer material, and a method for producing the same. A photoreactive polymer material represented by Chemical Formula 10 is applied on a substrate to form a film. In the film, the side chains of the polymer material are non-oriented, but when subjected to polarized light exposure using a device comprising an ultraviolet lamp, a power supply, and a polarizing element (for example, a Glan-Taylor prism), it follows the direction of the electric field oscillation of the irradiation light, and The crosslinking reaction proceeds selectively only between the side chain photosensitive components arranged in the direction perpendicular to the irradiation light traveling direction to fix the arrangement. Since they are not arranged in the direction of the electric field oscillation of the irradiation light and in the direction perpendicular to the direction of the irradiation light, the unreacted side chains are arranged in the same direction as the photoreacted portion due to the molecular motion after the polarization exposure. As a result, all the side chains in the polymer coating film are arranged in the direction of the electric field oscillation of the irradiation light and in the direction perpendicular to the direction of the irradiation light. By repeating the application of the polymer material and the exposure of polarized light in this manner, lamination is performed, and a birefringent film having an arbitrary phase difference and optical axis can be obtained. |
