Abstract
A liquid crystal panel includes a liquid crystal layer, a pixel electrode, and a common electrode. In a case where the AC voltage of a certain amplitude is supplied to the pixel electrode, an optimum common voltage fluctuates from a first optimum common voltage to a second optimum common voltage, the optimum common voltage being the common voltage that minimizes a transmittance difference between the transmittance of the pixel before a reversal of polarity of the pixel voltage and the transmittance of the pixel after the reversal of polarity of the pixel voltage. The common voltage is a voltage that is higher than the first optimum common voltage and lower than the second optimum common voltage or a voltage that is lower than the first optimum common voltage and higher than the second optimum common voltage.
