Abstract
In consideration of the current leakage path of a liquid crystal panel and a signal line voltage fluctuation due to the current leakage path, a γ adjusting function (second driving method) is applied for each divided period in the first driving method. In a signal line driving unit, a gray scale voltage obtained by adding or subtracting a voltage fluctuation value different in each of the output periods of each gray scale is generated, and a gray scale voltage taking the voltage fluctuation value into consideration is applied to a signal line.
