Display device, in particular for a vehicle, with switchable sharing and private modes

A display device, in particular for a vehicle, comprising

• an LCD display having a plurality of pixels which comprises a transparent carrier layer (10), on which, per pixel, a group of electrodes (12′, 13′, 13″, 18′) and also electronic components for actuating the electrodes (12′, 13′, 13″, 18′) are arranged, a transparent cover layer (22) forming a display surface, and a liquid crystals layer (24) between the carrier layer (10) and the cover layer (22),
• wherein each group of electrodes (12′, 13′, 13″, 18′) comprises a first electrode surface (12′) that can be connected to a ground potential and a split electrode surface having two coplanar second electrode surfaces (13′, 13″) that can be connected to the ground potential, are electrically insulated from one another and from the first electrode surface (12′), and are arranged above or below the first electrode surface (12′) such that side edges of the split electrode surface are flush with side edges of the first electrode surface in a side view,
• wherein each group of electrodes (12′, 13′, 13″, 18′) comprises a third electrode (18′), which is arranged to be electrically insulated from the first and second electrode surfaces (12′, 13′, 13″) and can be connected to an operating potential, and
• an actuation unit, which comprises the electronic components, inter alia, for connecting the third electrode (18′) of each pixel or selected pixels to the operating potential and for connecting the first electrode surfaces (12′) of each pixel or selected pixels to the ground potential in a sharing mode and for connecting the first electrode surface (12′) and additionally one of the two second electrode surfaces (13′, 13″) of each pixel or selected pixels to the ground potential in a private mode,
• as a result of which information displayed on the display surface of the LCD display, when looking at the display surface from a viewing direction facing one of the two second electrode surfaces (13′, 13″) of all the pixels, is visible in greater contrast in sharing mode than in private mode, in which the one of the two second electrode surfaces (13′, 13″) of each pixel or selected pixels which faces away from said viewing direction is connected to the ground potential.
