SUBSTRATE FOR VERTICAL ALIGNMENT AND PROCESS FOR PRODUCING VERTICALLY ALIGNED LIQUID CRYSTAL RETARDATION FILM

摘要

An alignment substrate capable of forming a vertically aligned liquid crystal retardation film through simple procedure without need to carry out special treatment; and a process for producing a vertically aligned liquid crystal retardation film with the use of the alignment substrate. Vertical alignment of a liquid crystal compound can be effected by providing a substrate for vertical alignment comprising a layer of inorganic substance and, superimposed on a surface thereof, a layer of acrylic polymer and applying a layer of liquid crystal compound on the substrate by coating operation, etc.
