Abstract

Se describe una composicion de alineacion optica que incluye una poliimida que tiene un grupo cinamato en su cadena lateral. También, se describe una capa de alineacion formada al utilizar la composicion y un dispositivo de pantalla de cristal líquido (LCD) que tiene la misma. La capa de alineacion tiene una excelente estabilidad térmica. De acuerdo a la presente invencion, puesto que se obtiene la capa de alineacion que tiene excelente estabilidad térmica, se puede fabricar una LCD tiene excelente desempeño.
