An electroluminescent device having a transparent substrate (1) extending in the lengthwise direction of the device, a transparent conductive layer placed on the back surface (2) of the transparent substrate (1), a luminescent layer (4) having a width smaller than the width of the transparent conductive layer (2) and being placed on the back surface of the transparent conductive layer (2), a rear electrode (3) placed on the back surface of the luminescent layer (4), and at least one buss (5) which is placed on the part of the back surface of the transparent conductive layer (2) having no luminescent layer, has a width smaller than the width of the transparent conductiver layer (2), and is electrically in contact with neither the luminescent layer (4) nor the rear electrode (3) in which the transparent conductive layer (2), the luminescent layer (4), the rear electrode (3) and the buss (5) continuously extend in the lengthwise direction of the transparent substrate (1).

L'invention concerne un dispositif électroluminescent constitué d'un substrat (1) transparent s'étendant dans le sens de la longueur du dispositif ; d'une couche conductrice transparente disposée sur la surface arrière (2) du substrat (1) transparent ; d'une couche (4) luminescente, dont la largeur est inférieure à celle de la couche (2) conductrice transparente, laquelle couche est placée sur la surface arrière de la couche (2) conductrice transparente ; d'une électrode (3) arrière placée sur la surface arrière de la couche (4) luminescente ; et d'au moins un bus (5) disposé sur la partie de la surface arrière de la couche (2) conductrice transparente non recouverte par la couche (4) luminescente, lequel bus a une largeur inférieure à celle de la couche (2) conductrice transparente et n'est en contact électrique ni avec la couche (4) luminescente, ni l'électrode (3) arrière. Dans ce dispositif, la couche (2) conductrice transparente, la couche (4) luminescente, l'électrode (3) arrière et le bus (5) s'étendent en continu dans le sens de la longueur du substrat (1) transparent.
