VERTICAL ALIGNMENT FILM AND METHOD OF MANUFACTURING THEREOF, VERTICAL ALIGNMENT SUBSTRATE AND METHOD OF MANUFACTURING THEREOF, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

A highly reliable vertical alignment film for aligning display-use liquid crystal molecules in a direction slightly tilted from the substrate normal line direction and a method of manufacturing the vertical alignment film are provided. A layer composed of a liquid crystalline monomer that has a crystalline framework, and that has characteristics to align the crystalline framework vertically to an interface with a dissimilar material and polymerizable characteristics is formed on a transparent substrate. A magnetic field is applied thereto while the liquid crystal state is maintained, and thereby the liquid crystalline framework of the liquid crystalline monomer is aligned in a direction slightly tilted from the normal line direction of the substrate. In this state, the liquid crystalline monomer is polymerized, and a hardened layer formed from a complex composed of the unreacted liquid crystalline monomer and a liquid crystalline monomer polymer is formed as a vertical alignment film.
