Beschreibung
Zusammenfassung:	A display device includes a support and first and second conductive electrical power supply elements, the first conductive element being arranged on the support. The display device also includes LED modules, each including at least one LED and two electrical power supply pads that are arranged on two opposite faces, respectively, of the LED module, one of which corresponds to an emissive face of the LED. The electrical power supply pads of each LED module are connected to the first and second conductive electrical power supply elements, respectively, and the connection area of an electrical power supply pad of an LED module for connection with the first conductive electrical power supply element is smaller than a receiving area of the first conductive element corresponding to the area of the first conductive element in a parallel plane to the connection areas of the power supply pads of the LED modules.
