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.

Abstract: A thin film integrated circuit consists of a first conductor of aluminum extended in any desired direction on an insulating substrate, an anodized film formed by anodization in a chromic acid solution at positions other than cross-connectional parts on the first conductor, a second conductor cross-connected on the first conductor, and an anodized film formed by anodization in a chromic acid solution on the surface of the second conductor. The thin film integrated circuit is prepared by partially forming an anodized film in a sulfuric acid or oxalic acid solution at cross-connectional parts of a first conductor of aluminum so as not to form any anodized film in a chromic acid solution at the cross-sectional parts of the first conductor of the circuit, masking the partially formed anodized film with a photoresist film, then forming an anodized film by a chromic acid solution, and then removing the photoresist film and the anodized film.
