Abstract
A viewing angle-controlling liquid crystal panel sequentially includes a first polarizing plate; a first liquid crystal panel; a second polarizing plate; a second liquid crystal panel; and a third polarizing plate, wherein an azimuthal angle φP1 of the absorption axis of the first polarizing plate, an azimuthal angle φ1 of a director of liquid crystal molecules near the first substrate and an azimuthal angle φ2 of a director of liquid crystal molecules near the second substrate in the first liquid crystal panel, an azimuthal angle φP2 of the absorption axis of the second polarizing plate, an azimuthal angle φ3 of a director of liquid crystal molecules near the third substrate and an azimuthal angle φ4 of a director of liquid crystal molecules near the fourth substrate in the second liquid crystal panel, and an azimuthal angle φP3 of the absorption axis of the third polarizing plate satisfy specific formulas.
