Abstract: According to one embodiment, a liquid crystal device includes a first liquid crystal cell and a second liquid crystal cell. The first liquid crystal cell and the second liquid crystal cell each include a first strip electrode, a second strip electrode, a third strip electrode and a fourth strip electrode. The extension direction of each of the first strip electrode and the second strip electrode in the first liquid crystal cell is different from the extension direction of each of the first strip electrode and the second strip electrode in the second liquid crystal cell. The extension direction of each of the first strip electrode and the second strip electrode is orthogonal to the extension direction of each of the third strip electrode and the fourth strip electrode.
