1. A display device, in particular for a vehicle, comprising
a display,
a backlighting unit for backlighting the display
wherein the backlighting unit comprises a plurality of light sources for backlight and a light guide plate having a light emission side facing the display, an opposite rear side and a circumferential side edge surface arranged between the light emission side and the rear side,
wherein the light sources are arranged next to the light guide plate in a laterally offset manner for feeding light through at least a partial area of the side edge surface of the light guide plate into the latter, and wherein backlight fed into the light guide plate from the side is emitted from the light emission side of the light guide plate, and
a proximity sensor system for sensing an object located in the area in front of the display,
wherein the proximity sensor system comprises at least one proximity sensor system transmitter element for transmitting invisible sensor radiation, in particular IR sensor radiation, and at least one proximity sensor system receiver element for receiving sensor radiation reflected from an object in the area in front of the display,
wherein the at least one proximity sensor system transmitter element is arranged laterally offset from an area of the side edge surface of the light guide plate and wherein the sensor radiation in this area is fed into the side edge surface of the light guide plate and is emitted from the light emission side of the light guide plate, and
wherein the at least one proximity sensor system receiver element is arranged inside the display, and/or directly between the display and the light guide plate, and/or behind the light guide plate configured to directly receive light transmitted through the light guide plate.
