Abstract

A viewing angle control liquid crystal panel includes: a first polarizer having a first absorption axis; a first liquid crystal panel including a first substrate, a first liquid crystal layer, and a second substrate; a second liquid crystal panel including a third substrate, a second liquid crystal layer, and a fourth substrate; and a third liquid crystal panel including a fifth substrate, a third liquid crystal layer, and a sixth substrate. The following equations are satisfied, where φP1 is an azimuth angle of the first absorption axis and φ1, φ2, φ3, φ4, φ5, and φ6 are azimuth angles of directors of liquid crystal molecules on first, second, third, fourth, fifth, and sixth substrate sides:0°≤|φ1−φ2|≤5°0°≤|φ1−φ1|≤5°0°≤|φ3−φ4|≤5°0°≤|φ5−φ6|≤5°.
