Keywords: LCD, photoalingnment


Reactive monomer(RM257) added photodecomposition polyimide film are exposed to linearly polarized UV. After irradiation, polyimide film gives LC alignment, perpendicular to polarization direction of the UV irradiation. LC aligning direction is measured by polar diagram. We had time to adjust during 10min-30min. And We exposed to linearly polarized UV the angle vertically or horizontally by measured the degree of LC alingnment.
