Abstract

Se describe una composicion de alineacion optica que incluye un primer polímero seleccionado de un polímero de la serie de cinamato y un polímero de la serie de cumarina y un segundo polímero seleccionado de una poliimida que tiene un grupo alquilo de cadena larga en sus cadenas laterales y poliimida que tiene un grupo alquilo en ambos de sus extremos, una capa de alineacion formada al utilizar la misma y una pantalla de cristal líquido que tiene la capa de alineacion. De acuerdo a la presente invencion, se mejora la estabilidad térmica de la capa de alineacion y el ángulo de preinclinacion característico del cristal líquido.
