  • Liquid crystal alignment layers
    Patent number: 4232946
    Abstract: Two alignment films are deposited on a liquid crystal substrate. Each film is deposited at an angle of about 5.degree. with respect to the substrate surface. The projection on the substrate of one deposition beam forms an angle of 180.degree. with the projecton on the surface of the other deposition beam.
