| 1. A substrate structure for a liquid crystal display device, comprising:
a substrate with an electrode layer thereon;
a first alignment layer disposed on the substrate; and
a second alignment layer selectively disposed on the first alignment layer;
wherein orientations of liquid crystal molecules on the first alignment layer and on the second alignment layer are different,
wherein the first alignment layer provides a vertical liquid crystal molecule orientation, wherein a longitudinal axis of
the liquid crystal molecule is pre-tilted 75-90 degrees against the first alignment layer; and
wherein the second alignment layer provides a horizontal liquid crystal molecule orientation, wherein a longitudinal axis
of the liquid crystal molecule is pre-tilted 0-15 degrees against the second alignment layer.
