Abstract
In a liquid crystal apparatus, a second substrate is provided with an optical compensation layer having inclined surfaces at a first substrate side. A liquid crystal layer includes liquid crystal molecules having negative dielectric anisotropy. While no voltage is applied to the liquid crystal layer, an angle between a long axis direction of the liquid crystal molecules and each of the inclined surfaces is set to an angle smaller than 90°.
