Abstract: An in-plane-switching liquid crystal display unit has a two-dimensional matrix of pixel regions each including a first auxiliary region and a second auxiliary region. When no electric field is applied, liquid crystal molecules in the first and second auxiliary regions are directed in respective orientations that lie at 90null with respect to each other. When a voltage is applied, the liquid crystal molecules are rotated in the same direction while maintaining their orientations in the first and second auxiliary regions at 90null with respect to each other. Alternatively, the liquid crystal molecules in the first and second auxiliary regions are directed in the same orientation when no electric field is applied, and when a voltage is applied, the liquid crystal molecules are rotated opposite directions while maintaining their orientations in symmetric relationship.
