Abstract: Provided is a liquid crystal display device in which both a vertical electric field and a horizontal electric field are used and flickering is hardly recognized. The liquid crystal display device includes a liquid crystal panel and a control unit. The control unit includes a horizontal electric field control unit and a vertical electric field control unit. The horizontal electric field control unit controls the potentials of pairs of drive electrodes included in the liquid crystal panel, and thereby controls a horizontal electric field that is generated between each pair of drive electrodes. The vertical electric field control unit controls the potentials of a common electrode and an opposite electrode included in the liquid crystal panel, and thereby controls a vertical electric field that is generated between the common electrode and the opposite electrode. The horizontal electric field control unit controls the intensity and the polarity of the horizontal electric field when the vertical electric field control unit is causing the vertical electric field to be generated. The vertical electric field control unit inverts the polarity of the vertical electric field when the horizontal electric field control unit is maintaining the polarity of the horizontal electric field.
