Abstract:
1. A liquid crystal device, comprising: a pair of polarizing plates having a transmission axis; a display panel being disposed between the pair of polarizing plates and having a function of displaying an image; and a viewing angle control panel having a liquid crystal layer that is disposed at a position adjacent to one of the pair of polarizing plates between the pair of polarizing plates with liquid crystal molecules aligned in a predetermined direction and controlling a viewing angle of a display on the display panel, wherein the display panel has a liquid crystal layer in which the dielectric anisotropy is negative and has a vertical alignment mode in which circularly polarized light is emitted toward the viewing angle control panel, wherein a phase difference film for converting the circularly polarized light into linearly polarized light is provided between the display panel and the viewing angle control panel, and wherein the alignment direction of the liquid crystal molecules of the viewing angle control panel is substantially parallel or perpendicular to a transmission axis of the one polarizing plate.
