L'invention concerne un panneau d'affichage qui comprend : un corps électroluminescent qui émet de la lumière; un substrat électrique qui laisse passer la lumière et a une première surface et une seconde surface sur l'envers de la première surface, la première surface comprenant un point de contact électrique, au niveau duquel est monté le corps électroluminescent, et un câblage relié électriquement au point de contact électrique; une plaque de surface avant ayant une surface de collage sur laquelle est collée la première surface du substrat électrique, une section de logement qui loge le corps électroluminescent et fait face au corps électroluminescent, et une concavité qui a une surface de réflexion qui réfléchit la lumière émise par le corps électroluminescent logé vers la direction du corps électroluminescent; et un élément d'affichage qui a une première surface plate faisant face à la seconde surface du substrat électrique, et une autre surface plate qui est la surface inverse de la première surface plate, et l'élément d'affichage comprenant un site de transmission de lumière qui exprime une couleur prédéterminée au moyen de la lumière transmise qui a été réfléchie par la surface de réflexion et transmise à travers le substrat électrique passant de la première surface plate à l'autre surface plate.
