Abstract
A liquid crystal display device includes, in the given order: a first substrate; a liquid crystal layer containing liquid crystal molecules; and a second substrate; wherein the first substrate includes a first electrode, a second electrode positioned closer to the liquid crystal layer than the first electrode is, and an insulating film between the first electrode and the second electrode, the second electrode has an opening having a shape including an elliptical portion and/or a circular portion, in a no-voltage-applied state, where no voltage is applied between the first electrode and the second electrode, the liquid crystal molecules are aligned parallel to the first substrate, and in a plan view, the major axis of the elliptical portion is parallel or perpendicular to the alignment azimuth of the liquid crystal molecules in the no-voltage-applied state.
