Abstract

This invention is to provide a vertical orientation type composition having excellent heat resistance, transparency, surface hardness and vertical orientation, to provide a liquid crystal oriented film using the same, and to provide a liquid crystal cell. The vertical orientation type composition containing a low polar polyamic acid resin, the liquid crystal oriented film and the liquid crystal cell using the same are provided. In more detail, a new polyamic acid-mixed composition has excellent heat resistance, surface hardness, transparency and liquid crystal orientation and prepared by mixing a polyamic acid derivative with a low polar polyamic acid resin in a proper ratio, in which the low polar polyamic acid resin is prepared by solution-polymerizing an acid dianhydride with aromatic diamines containing an imide ring-containing side chain-having aromatic diamine. The liquid crystal oriented film has low surface roughness and highly excellent printability, heat resistance and transparency using the polyamic acid composition. The liquid cell has a pretilt angle of ≥ 89 DEG and a voltage retention of ≥ 99%.
