Abstract:
An apparatus for forming an alignment layer to be used for liquid crystal displays each having at least two substrates with liquid crystals sealed therebetween, the apparatus comprising a deposition chamber for forming an alignment layer of oxide silicon (SiOx: 1.0&lE;Ã—&lE;2.0) on at least one of the two substrates under a requirement 0&lE;&Dgr;&thgr;&lE;3Â° in &Dgr;&thgr;=tanâˆ’1(dcos &thgr;/(D+dsin &thgr;)) in which â€œdâ€  is a distance from the substrate center to the center of a substrate edge required for alignment-layer deposition and â€œDâ€  is a distance from the substrate center to the center of an evaporation source containing the oxide silicon for alignment-layer deposition, and &thgr; is an angle formed between a direction in which a normal line extends on the substrate center and another direction in which evaporated particles of oxide silicon are deposited on the substrate center from the evaporation source.
