ABSTRACT:
There are provided a viewing angle control device that can provide a black display without coloring and achieve a significantly improved shielding ability during a narrow viewing angle state, and a display using the same. In order to adjust 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, the viewing angle control liquid crystal panel (2) includes a translucent dielectric film (206g,206r) for adjusting the voltage-transmittance characteristics of the liquid crystal at a position corresponding to a picture element of at least one color in a display liquid crystal panel (1) on at least one of a pair of translucent substrates (201, 202) that sandwich the liquid crystal therebetween.
