Abstract: According to an aspect, a pressure bonding device is configured to bond, to a plate-like first workpiece having a curved surface part, a plurality of plate-like second workpieces smaller than the first workpiece. The pressure bonding device includes: a vacuum chamber; a stage disposed in the vacuum chamber and having a shape extending along a first surface of the curved surface part of the first workpiece so as to fix the first surface on the stage; and a bonding unit configured to deform an elastic diaphragm by internal pressure and pressure-bond one of the second workpieces to a second surface of the first workpiece. A plurality of the bonding units are disposed facing the stage.

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.
