A driving method for a liquid crystal device, which has a first electrode, a second electrode, and a third electrode for trapping ions, includes applying AC signals having the same frequency but whose phases in an amount of time corresponding to a single cycle are shifted relative to each other to the first electrode, the second electrode, and the third electrode, respectively, so that the distribution of an electrical field produced between the first electrode, the second electrode, and the third electrode is scrolled from the first electrode to the third electrode over time. |

1. A liquid crystal device driving method, the liquid crystal device including:
a first substrate and a second substrate that are disposed opposing each other and are laminated to each other using a sealant; a liquid crystal layer interposed between the first substrate and the second substrate; a pixel electrode provided in a display region of the first substrate; an opposing electrode provided in the first substrate or the second substrate so as to oppose the pixel electrode; and a first electrode that, when viewed from above, is provided between the display region and the sealant and to which a first potential is supplied, a second electrode that, when viewed from above, is provided between the first electrode and the sealant and to which a second potential is supplied, and a third electrode that, when viewed from above, is provided between the second electrode and the sealant and to which a third potential is supplied, the first electrode, the second electrode, and the third electrode being provided in the first substrate or the second substrate, and the method comprising applying AC signals having the same frequency to the first electrode, the second electrode, and the third electrode, respectively, so that: the second potential shifts from a positive-polarity or a reference potential to a negative-polarity after the first potential has shifted from the positive-polarity or the reference potential to the negative-polarity but before the first potential shifts to the reference potential or the positive-polarity; the third potential shifts from the positive-polarity or the reference potential to the negative-polarity after the second potential has shifted to the negative-polarity but before the second potential shifts to the reference potential or the positive-polarity; the second potential shifts from the negative-polarity or the reference potential to the positive-polarity after the first potential has shifted from the negative-polarity or the reference potential to the positive-polarity but before the first potential shifts to the reference potential or the negative-polarity; and the third potential shifts from the negative-polarity or the reference potential to the positive-polarity after the second potential has shifted from the negative-polarity or the reference potential to the positive-polarity but before the second potential shifts to the reference potential or the negative-polarity. |
