PROBLEM TO BE SOLVED: To efficiently perform adjustment of a common voltage applied to a common electrode of a liquid crystal display panel.SOLUTION: A common voltage adjustment device (100) includes: a common voltage setting unit (150) which sets a common voltage set to a common electrode, to a liquid crystal display panel; a flicker measurement unit (130) which measures a flicker value indicative of the degree of flicker on the liquid crystal display panel; and a control unit (140) which acquires the measured flicker value and instructs the common voltage setting unit to set a common voltage. After acquiring the flicker value from the flicker measurement unit, the control unit instructs the common voltage setting unit to set a measurement common voltage being a common voltage to be next measured, calculates an interpolation curve showing the variation in flicker value due to the measurement common voltage on the basis of a plurality of acquired flicker values, calculates a minimum value of flicker values on the interpolation curve as a panel common voltage, and instructs the common voltage setting unit to set the panel common voltage. |
