Abstract
A viewing angle controlling liquid crystal panel in which uniformity of a shielding effect in a screen is further improved is provided. Linearly polarized light enters a liquid crystal layer. Further, the liquid crystal layer is provided, on a light exit side of the liquid crystal layer, with a polarizing plate transmitting only a component of light having exited from the liquid crystal layer which component is parallel to a polarization axis of the linearly polarized light having entered the liquid crystal layer. Liquid crystal molecules contained in the liquid crystal layer are tilted in a direction parallel to or perpendicular to the polarization axis of the linearly polarized light having entered the liquid crystal layer. In addition, an electrode () is provided so that two or more different voltages can be applied to the liquid crystal layer simultaneously.
