Claim:
1. A liquid crystal display device, comprising: a first substrate; a first alignment layer formed on the first substrate; a second substrate; a second alignment layer formed on the second substrate; and a liquid crystal layer disposed between the first and second alignment layers and comprising liquid crystals of a helical structure in which a helical axis of the helical structure is parallel to the first and second substrates, at least one of the first and second alignment layers including a first region, a second region and a third region, the second region disposed between the first and the third region, a pretilt angle of the first region being about 0 degree, a pretilt angle of the third region being about 90 degrees, a pretilt angle of the second region being between 0 degree and 90 degrees, a change of the pretilt angles of the first through third regions being defined as a graduation distribution.
