Claim 0:
1. A display device comprising an integrated, optically operating proximity sensor system for detecting an object, including a hand or a finger of a person's hand, present within an observation space in front of the display device, for gesture recognition and/or far-field sensing, the display device being provided with
a display unit having a front side with a display surface displaying information, an edge region adjacent to the display surface and not used for the display of information, and a rear side, and
a proximity sensor system comprising at least one transmitter for emitting sensor radiation into the observation space, and comprising at least one receiver for receiving sensor radiation effected from the observation space,
wherein
the at least one transmitter of the proximity sensor system is arranged below the display unit, or below the region occupied by the display surface, or, on the rear side of the display unit or facing the rear side of the display unit or in the display unit, and the at least one receiver of the proximity sensor system is arranged in the edge region adjacent to the display surface on the front or the rear side of the display unit,

the display unit comprising a thin film transistor (TFT) display panel having an upper side forming the front side of the display unit which comprises an area aligned with the display surface and having TFT transistors forming the display surface, and a protrusion region surrounding this area and forming the edge region, and having a lower side facing away from the upper side, and comprising a color filter layer arranged above or on the upper side of the display panel,
wherein
the at least one receiver of the proximity sensor system is arranged within the protrusion region of the display panel on the upper or the lower side thereof, and

the at least one receiver and/or the at least one transmitter of the proximity sensor system each being configured as a semiconductor diode comprising semiconductor layers formed in TFT technology on the display panel and arranged side-by-side or above each other with abutting each other.
