Abstract

See full text

Provided is a liquid crystal device including: a liquid crystal panel including a first substrate having a first vertical alignment film, a second substrate having a second vertical alignment film, a liquid crystal layer which is interposed between the first vertical alignment film and the second vertical alignment film and has a negative dielectric anisotropy, a first polarizing plate that is disposed on a light-incident side of the liquid crystal layer, and a second polarizing plate that is disposed on a light-emitting side of the liquid crystal layer; an illuminating device which is disposed on a light-incident side of the liquid crystal panel, and emits light toward the liquid crystal panel; and a light control member which is disposed on a light-emitting side of the liquid crystal panel, and diffuses light that is emitted from the liquid crystal panel in an azimuth angle direction and a polar angle direction viewed from a normal direction of the liquid crystal panel to control an emission direction of the light. The liquid crystal panel includes a plurality of pixels, each being a basic unit of display, and each of the pixels has a plurality of regions in which a director direction or an alignment of liquid crystal molecules at a central portion of the liquid crystal layer in a thickness direction during application of a voltage is different.
