Abstract

La présente invention concerne un dispositif électroluminescent apte à rayonner efficacement la chaleur, sans accumulation de chaleur dans le dispositif, et un dispositif d'affichage comportant le dispositif électroluminescent. Une unité de rétroéclairage (1) comprend un élément cadre (13) comportant une partie inférieure en forme de plaque plane (131), une pluralité de substrats imprimés (12) disposés sur la partie inférieure (131), une pluralité de puces de DEL (111a) en agencement linéaire sur chacun des substrats imprimés (12) et une pluralité d'éléments réfléchissants (113) placés sur chacun des substrats imprimés (12) de manière à entourer chacune des puces de DEL (111a). La pluralité de substrats imprimés (12) est disposée sur la partie inférieure (131) de l'élément cadre (13) de manière à ménager un premier espace (I1) dans une première direction (X1) et un second espace (I2) dans une seconde direction (X2) orthogonale à la première direction (X1).
