Abstract
A method of aligning an alignment layer of a liquid crystal display (LCD) includes positioning a substrate on a stage; the substrate having the alignment layer provided thereon and the alignment layer including a plurality of alignment regions. Data identifying positions of the alignment regions relative to the alignment layer are loaded. A control signal for controlling a supply of light based on the loaded data identifying the positions of the alignment regions is generated. The light is supplied to the alignment regions according to the control signal and the alignment regions are aligned. The light is supplied from at least two different angles of incidence so that the alignment regions are aligned in at least two different directions.
