Abstract

In a liquid crystal device, in an area located between a pixel area and a sealing material in plan view in a first substrate, a first electrode, a second electrode, and a third electrode are provided sequentially from the pixel area toward the sealing material, the first electrode being supplied with a first signal, the second electrode being supplied with a second signal having a phase different from the first signal, and the third electrode being supplied with a third signal having a phase different from those of the first signal and the second signal. Here, a distance (first distance) from a pixel electrode, which is adjacent to the first electrode, among a plurality of pixel electrodes to the first electrode is equal to or less than a distance (second distance) from the first electrode to the second electrode.

Dependent claims

A liquid crystal device comprising:

a first substrate;
a second substrate bonded to the first substrate via a sealing material;
a liquid crystal layer disposed in a space surrounded by the sealing material between the first substrate and the second substrate;
a plurality of pixel electrodes provided in a pixel area in the first substrate;
a first electrode provided at one of the first substrate and the second substrate and supplied with a first signal in an area located between the pixel area and the sealing material in plan view;
and
a second electrode provided at the one of the first substrate and the second substrate and supplied with a second signal having a phase different from that of the first signal in an area located between the first electrode and the sealing material in plan view, wherein
a first distance being a distance from a pixel electrode, which is adjacent to the first electrode, among the plurality of pixel electrodes to the first electrode is equal to or less than a second distance from the first electrode to the second electrode.
