Abstract
A liquid crystal device includes: a pair of substrates; a liquid crystal layer sandwiched between the pair of substrates; a display pixel and a viewing-angle control pixel that are substantially rectangular and disposed on at least one of the pair of substrates; a first electrode and a second electrode disposed in the viewing-angle control pixel; and a plurality of strip-like electrode portions that are provided to at least either the first electrode or the second electrode and spaced from one another across a width direction of the viewing-angle control pixel, the liquid crystal device being configured so that an electric field is generated between the first electrode and the second electrode to control the direction of alignment of liquid crystal molecules in the liquid crystal layer, thereby changing the luminance of the viewing-angle control pixel in a direction oblique to the front.
