概要
- 論文の詳細を見る
We report an anisotropy-enhanced polyimidization method in which the alignment surface coated with polyamic acid is ion beam-treated before polyimidization. The alignment substrate made by this method shows larger optical anisotropy than the rubbed and conventional ion beam-treated surfaces. Nematic liquid crystal (NLC) molecules are homogeneously aligned along the direction of the polyimidization. The LC cells fabricated by this method have lower pretilt angle and stronger anchoring energy than the cells fabricated by ion beam and rubbing method.
