  • Publication number: 20040223105
    Abstract: An alignment layer to be used for liquid crystal displays each having at least two substrates with liquid crystals sealed therebetween is formed as follows: The substrates placed on each of several substrate trays are heated in a first load-lock chamber. At least one of the two substrates is irradiated with evaporated particles of oxide silicon (SiOx: 1.0≦x≦2.0) by vacuum deposition at an angle in the range from 45° to 60° from a direction of the normal line on the substrate surface to form an alignment layer thereon while the substrate trays are being moved in a layer-deposition chamber intermittently or sequentially. The substrate trays are cooled in a second load-lock chamber, thus producing substrates each formed the alignment layer thereon.
