Abstract: Provided is a liquid crystal display device that employs a horizontal alignment mode providing wide viewing angles and is capable of achieving high-speed response and high transmittance. The liquid crystal display device includes a pair of substrates with fringe electric field structures and a liquid crystal layer interposed between the paired substrates. Each fringe electric field structure includes a planar electrode, a slit electrode, and an insulating film interposed between the planar electrode and the slit electrode. The liquid crystal layer includes liquid crystal molecules that align horizontally to the substrate surfaces of the paired substrates with no voltage applied. The liquid crystal molecules in the vicinity of the respective substrates are configured to rotate in the same direction from the alignment azimuth with no voltage applied when voltage is applied to each of the fringe electric field structures.
