Provided is a liquid crystal display device having a horizontal orientation mode having both high-speed response and a high transmittance. This liquid crystal display device comprises, in order, a first substrate, a liquid crystal layer containing liquid crystal molecules, and a second substrate. The first substrate has a first electrode, a second electrode provided further on the liquid crystal layer-side than the first electrode, and an insulating film provided between the first electrode and the second electrode. An opening including an elliptical section and/or a circular section is formed in the second electrode. In a no-voltage state in which voltage is not applied between the first electrode and the second electrode, the liquid crystal molecules are oriented parallel to the first substrate and, in the planar view, the major axis of the elliptical section and the orientation direction of the liquid crystal molecules in the no-voltage state are parallel or orthogonal. |
