  • Method of forming alignment film for liquid crystal display cell
    Patent number: 4043647
    Abstract: A liquid crystal display cell being capable of display with liquid crystal molecules aligned towards a predetermined direction has its display characteristics made greatly dependent on the properties of an alignment film coming into contact with the molecules of the liquid crystal. A louver having a predetermined angle is disposed between the substrate on which the alignment film is to be formed and an evaporation material source to pass a material evaporated from the evaporation material for deposition onto the substrate. The thus formed film exhibits a very great orientation controlling power of biaxial anisotropy. This forming method of the alignment film also allows the easy formation of the alignment film on a large substrate.
