Abstract: A liquid crystal display device is fabricated by forming a first alignment layer on a first base substrate. A second alignment layer is formed on a second base substrate. A liquid crystal is disposed on one of the first alignment layer and the second alignment layer. The first base substrate and the second base substrate are combined. At least one of the first alignment layer and the second alignment layer is formed by forming an alignment solution on a corresponding base substrate. An alignment layer is formed by curing the alignment solution. The alignment layer is aligned by radiating a light onto the base substrate, first cleaning the base substrate, and baking the alignment layer.
