COMB-LIKE POLY(OXYETHYLENE)/CONJUGATED POLYMER BLENDS AND LIQUID CRYSTAL ALIGNMENT LAYERS USING THE SAME

摘要

PURPOSE: A comb-like polyoxyethylene-based polymer/conjugate polymer blend is provided to stably maintain the alignment of a liquid crystal for long time, thereby being capable of increasing the efficiency of a liquid crystal display device. CONSTITUTION: A comb-like polyoxyethylene-based polymer/conjugate polymer blend comprises 100.0 parts by weight of a polymer indicated in chemical formula 1, and 10-90 parts by weight of a conjugated polymer which consists of one or more polymers selected from polymers indicated in chemical formula 2, 3, 4, or 5. A liquid crystal device comprises: an upper and lower substrate which faces each other; a transparent electrode formed on the upper and lower substrate; and a liquid crystal layer formed between the alignment film; and a liquid crystal alignment film which has a liquid crystal layer formed between the alignment films and is formed of the polymer blend.
