Abstract:
A liquid crystal display device including a pair of substrates, a first alignment layer formed on one substrate and a second alignment layer formed on the other substrate, and a plurality of pixels, each having four different alignment regions. The first alignment layer is treated to define two different pretilt directions for the liquid crystal molecules within the four alignment regions, wherein the two different pretilt directions are opposite each other and both extend in a generally parallel direction to a first boundary defined between two regions in which the two different pretilt directions are defined, and said second alignment layer defines another two different pretilt directions within the four alignment regions, wherein the two different pretilt directions are opposite each other and both extend in a generally parallel direction to a second boundary defined between two regions in which the another two different pretilt directions are defined.
