发明名称 Viewing angle control device and display provided with the same
摘要 There are provided a viewing angle control device that can provide a pure black display without coloring and have a significantly improved shielding ability in the narrow viewing angle state, and a display using the viewing angle control device. To adjust the VT (voltage-transmittance) characteristics of 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 using birefringence of liquid crystal, translucent electrode films (205r, 205g, 206b), to which alternating-current voltages with different frequencies are applied, are provided on a portion of at least one of a pair of translucent substrates (201, 202) sandwiching the liquid crystal, the portion corresponding to at least one color of a picture element of a display liquid crystal panel (1), so that the voltage-transmittance characteristics of the liquid crystal are adjusted.
