摘要 |
A method for producing an optical orientation film is disclosed, the method being able to realize highly accurate exposure in a pattern, even if a simple device and non-parallel light are used and a long continuous resin substrate is used and fed continuously. The method for producing the optical orientation film includes the steps of: (i) preparing an irradiation target substrate and a long continuous photomask (ii) feeding the irradiation target substrate continuously; (iii) feeding the photomask continuously; (iv) producing a laminate by laminating the photomask fed in step (iii) on an orientation layer of the irradiation target substrate fed in step (ii); (v) exposing the orientation layer in the pattern by irradiating with light, while feeding the laminate obtained in step (iv) in the longitudinal direction of the laminate; and (vi) removing the photomask from the laminate irradiated in step (v).
