Abstract:
A method of forming an alignment layer to be used for liquid Crystal displays each having at least two substrates with liquid crystals sealed therebetween, the method comprising the steps of:heating the substrates placed on each of several substrate trays in a first load-lock chamber; irradiating at least one of the two substrates with evaporated particles of oxide silicon (SiOx: 1.0&lE;Ã—&lE;2.0) by vacuum deposition at an angle in the range from 45Â° to 60Â° from a direction of a 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; and cooling the substrate trays in a second load-lock chamber, thus producing substrates each formed the alignment layer thereon.
