Abstract: According to an aspect, a display device includes: a display panel having a display area including pixels; a light source device configured to emit light from an emission area overlapping the display area toward the display panel; a dimming panel between the display panel and the light source device and configured to adjust brightness of emission light emitted from the emission area; and a drive circuit configured to drive the dimming panel. The emission area has a first emission area and a second emission area. The drive circuit is configured to, when gradation values of first pixels corresponding to the first emission area are equal to gradation values of second pixels corresponding to the second emission area, make transmittance of a second dimming area corresponding to the second pixels higher than that of a first dimming area corresponding to the first pixels in the dimming area.

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 an aspect, a display device includes: a cover member curved when viewed in a first axis direction along a first axis; and a display panel disposed on one side of the cover member. The cover member has a first surface facing the display panel and a second surface on the opposite side of the first surface. The first surface forms a straight line and at least a part of the second surface forms a curved line in a cross-section orthogonal to a second axis that is along a straight line extending from one end to the other end of the cover member when viewed in the first axis direction.
