Abstract
An LCD having the liquid crystal in at least a portion of the interpixel region displaced by a spacer material. The spacer material has a low dielectric constant relative to the liquid crystal, thus further impeding the formation of a bend deformation in the liquid crystal in the interpixel region when pixels on opposite sides of the spacer material are operating in the inversion mode. This elimination of the bend deformation in the interpixel region eliminates the reverse tilt disclination.
