Abstract: The present invention discloses an alignment substrate that includes a base substrate and an alignment layer arranged on the base substrate. A plurality of unit pixels is defined in the base substrate. The alignment layer includes at least two sub-alignment portions dividing the unit pixel into at least two domains. Each sub-alignment portion is arranged in a different domain of the at least two domains and is aligned to have a different pretilt direction from the other sub-alignment portions.
