Provided is a liquid crystal display device including a first substrate on which a first alignment layer is formed, a second substrate on which a second alignment layer is formed, and a liquid crystal layer disposed between the first and second alignment layers and including liquid crystals of a helical structure in which a helical axis is parallel to the first and second substrates. At least one of the first and second alignment layers has a graduation distribution profile of a pretilt angle which ranges from about 0 degrees to about 90 degrees.
