Abstract
A liquid crystal display is provided having two substrates. One substrate includes active aperture areas and a non-active area. A spacing layer is provided between the two substrates and includes spacing elements of anisotropic shape and geometry. The anisotropic spacing elements are formed only within the non-active areas of the substrate. A method of manufacturing is also provided including mechanically rubbing the liquid crystal display after the spacing elements are formed on the one substrate.
