Alignment coating liquid and application thereof

The invention discloses alignment coating liquid and application thereof. The alignment coating liquid comprises the following raw material components in percentage by mass: 8-15% of a liquid crystal guiding agent; 60%-85% of a solvent; and 3-8% of a surfactant. The alignment coating liquid takes a liquid crystal guiding agent as a main component and can be used for aligning a liquid crystal layer formed by the liquid crystal coating liquid, so that the alignment coating liquid can be used for preparing a liquid crystal thin film, an aligned alignment layer is prepared by the alignment coating liquid during preparation, and then the liquid crystal coating liquid is coated, so that the liquid crystal thin film is prepared. The liquid crystal layer with a multi-layer liquid crystal lattice structure can be obtained, Bragg reflection occurs, and therefore the liquid crystal film with the magical color effect is obtained. 本发明公开了一种配向涂布液及其应用，包括以下质量百分数的原料组分：液晶引导剂：8～15%；溶剂：60～85%；表面活性剂：3～8%。该配向涂布液由液晶引导剂为主要成分，可为液晶涂布液形
