To clarify the pretilt angle generation mechanism in photo-alignment method, we investigated the anisotropic properties of photo-alignment polymer PVCN-F, poly (vinyl fluoro cinnamate), and flowing induced pretilt angle. We measured the dichroic UV absorption and birefringence of photo-alignment layer to evaluate the degree of the photo induced anisotropy. It was observed that the UV exposure time dependence of birefringence and UV dichroism of PVCN-F shows the similar tendency. The anisotropy of PVCN-F increases rapidly in the beginning as the UV exposure time increase. The pretilt angle with considerable magnitude (more than 3°) appears in saturation region of anisotropy. It is shown that there is no direct relationship between anisotropy and pretilt angle. Therefore, these two properties seem to have the independent behavior each other.
