Title:
EXPOSURE METHOD AND EXPOSURE DEVICE, AND METHOD FOR FORMING OPTICAL ANISOTROPIC LAYER
Document Type and Number:
WIPO Patent Application WO/2023/085257
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an exposure method and an exposure device which make it possible to obtain a photo-alignment film having a high-accuracy alignment pattern, and a method for forming an optical anisotropic layer. The problem is solved by collecting linearly polarized light in a ring shape by an optical member, and when a film having a compound having a photo-alignable group is exposed, relatively moving the film and the optical member in a direction inclined with respect to the optical axis of the optical member while rotating the polarization direction of the polarized light.
