Abstract
In a liquid crystal device, a plurality of pixel electrodes are provided in a pixel region E, in a first substrate. The first substrate is provided with a first electrode interposed between the pixel region and a sealing material in a plan view, and a second electrode interposed between the first electrode and the sealing material in a plan view. Of the plurality of pixel electrodes, a first signal of a first phase is supplied to a first pixel electrode that is adjacent to the first electrode, a second signal of a second phase having a phase delay with respect to the first signal is applied to the first electrode, and a third signal of a third phase having a phase delay with respect to the second signal is applied to a second electrode.
