Abstract
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.

A liquid crystal display device comprising:
- a segment driver that commonly applies, when sequentially scanning a plurality of lines included in a liquid crystal display element to draw an image, a voltage according to image data of the image to a drawing line, a previous drive line, and a non-selection line included in the plurality of lines;
- a common driver that individually applies voltages to the drawing line, the previous drive line, and the non-selection line;
- and
- a voltage setting unit that sets a voltage that is applied from the segment driver and a voltage that is applied from the common driver, in such a manner that a molecular structure of the liquid crystal display element corresponding to the previous drive line becomes a focal conic state regardless of the image data by applying a synthesized voltage of the voltage that is applied from the segment driver and the voltage that is applied from the common driver to the previous drive line.
