Abstract
The invention relates to a display device including a printed circuit board and a number of light-emitting diodes, wherein a structured copper coating is provided on the printed circuit board. The copper coating has shielding regions which reduce or prevent penetration of light emitted downwards from the light-emitting diodes into the printed circuit board. This reduces or prevents emergence of light from the printed circuit board again at undesired locations.
