Patent attributes
A method for producing a liquid crystal display device including a pair of substrates, an electrode and an alignment layer formed on each substrate and a liquid crystal filled between the substrates, where at least one alignment layer exhibits a vertically orienting property. The method includes alignment-treating at least one of the alignment layers by irradiating the alignment layer exhibiting a vertically orienting property with ultraviolet rays, in two different directions, by providing two lamps for projection of ultraviolet rays. Also disclosed is manufacturing equipment for orienting an alignment layer of a liquid crystal display device, including a first lamp and a second lamp located at a different position than the first lamp, but on the same side of the alignment layer. Also, both lamps irradiate different ultraviolet rays that are within ±10 degrees of parallelism, and the first and second lamps irradiate ultraviolet rays in two different directions.
