摘要： A liquid crystal display device includes a segment driver, a common driver, and a voltage setting unit. The voltage setting unit derives a voltage at which a previous drive line becomes a focal conic state regardless of image data by applying a synthesized voltage of a voltage that is applied from the segment driver and a voltage that is applied from the common driver to the previous drive line. Then, the voltage setting unit sets the voltages that are applied from the segment driver and the common driver on the basis of the derived result.
