A liquid crystal display device includes: a liquid crystal panel that includes a first substrate having a first vertical alignment film, a second substrate having a second vertical alignment film, a liquid crystal layer having a negative dielectric anisotropy, a first polarizing plate, and a second polarizing plate; an illuminating device; and a light control member that is disposed on a light emission side of the liquid crystal panel. The light control member diffuses light that is emitted from the liquid crystal panel in an anisotropic manner in an azimuth angle direction viewed from a normal direction of the liquid crystal panel to control an emission direction of the light. A pixel, which is included in the liquid crystal panel, includes a first region in which a director of liquid crystal molecules at the central portion in a thickness direction of the liquid crystal layer during application of a voltage heads for a first orientation in a first direction, and a second region in which the director of the liquid crystal molecules at the central portion in the thickness direction of the liquid crystal layer during application of a voltage heads for a second orientation opposite to the first orientation in the first direction. An azimuth angle direction in which light-diffusibility of the light control member is relatively strong, and the first direction approximately match each other. |

1. A liquid crystal display device, comprising:
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 incidence side of the liquid crystal layer, and a second polarizing plate that is disposed on a light emission side of the liquid crystal layer; an illuminating device which is disposed on a light incidence 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 emission side of the liquid crystal panel, and diffuses light that is emitted from the liquid crystal panel in an anisotropic manner in an azimuth angle direction viewed from a normal direction of the liquid crystal panel to control an emission direction of the light, wherein the liquid crystal panel includes a plurality of pixels, each being a basic unit of display, the pixel includes a first region in which a director of liquid crystal molecules at the central portion in a thickness direction of the liquid crystal layer during application of a voltage heads for a first orientation in a first direction, and a second region in which the director of the liquid crystal molecules at the central portion in the thickness direction of the liquid crystal layer during application of a voltage heads for a second orientation opposite to the first orientation in the first direction, and an azimuth angle direction in which light-diffusibility of the light control member is relatively strong, and the first direction approximately match each other. |
