VIEWING ANGLE CONTROL DEVICE AND DISPLAY PROVIDED WITH THE SAME

摘要

It is an object to provide a viewing angle control device that can display a pure black without coloration in a narrow viewing angle state and is significantly improved in shielding capability in the narrow viewing angle state, and a display using the viewing angle control device. In a viewing angle control liquid crystal panel (2) that switches a viewing angle between a wide viewing angle state and a narrow viewing angle state by making use of birefringence of a liquid crystal, in order to adjust a VT (voltage-transmittance) characteristic of the viewing angle control liquid crystal panel (2), an optically transmissive electrode films (205r, 205g, 206b) to which alternative current voltages with mutually different frequencies are applied to adjust the voltage-transmittance characteristic of the liquid crystal is provided at a portion corresponding to at least one pixel of a liquid crystal display panel (1) on at least one side of a pair of optically transmissive substrates (201, 202) for holding the liquid crystal.
