Abstract
A liquid crystal panel includes a first substrate, a second substrate disposed to face the first substrate, a liquid crystal layer that is located between the first substrate and the second substrate and contains liquid crystal molecules, a pair of electrodes that apply a voltage to the liquid crystal layer, and a voltage control unit that performs control to alternately apply a first voltage having a first absolute value and a second voltage having a second absolute value different from the first absolute value between the pair of electrodes.
