The invention relates to a display device (210) which is provided with a display (212) and a backlighting unit (218) arranged behind the display (212). The backlighting unit (218) comprises a light guide plate (222) which has an upper light guide plate element (222a) and a lower light guide plate element (222b). Backlight (230) of light sources (220) is fed laterally into the upper light guide plate element (222a), which is emitted from the light emission side (228) of the light guide plate (222) after deflection and scattering within the light guide plate element (222a). Sensor radiation is fed into the lower light guide plate element (222b) by means of proximity sensor system transmitter elements (236), wherein said sensor radiation is likewise emitted from the light emission side (228) of the light guide plate (222) after reflection and scattering. Both light guide plate elements (222a, 222b) are optimized for the wavelengths of the radiation which is fed into the latter. The lateral arrangement of the proximity sensor system transmitter elements (236) and the light sources (220) results in a space-saving arrangement. After reflection on an object located in front of the display (212), the sensor radiation reaches the proximity sensor system receiver elements (238).
