L'invention concerne un panneau électroluminescent plat (40) présentant une pluralité d'éléments électroluminescents plats disposés linéairement sur le même substrat transparent (11) à des intervalles prescrits, lesdits éléments électroluminescents plats étant configurés de telle manière qu'une couche électroluminescente est disposée entre une première couche d'électrode et une seconde couche d'électrode. Les éléments électroluminescents plats sont connectés électriquement les uns aux autres en série. La pluralité d'éléments électroluminescents plats est recouverte par un élément d'étanchéité sur le substrat transparent (11). Des lignes de coupe imaginaires (CL) destinées à être utilisées lors de la coupe du panneau électroluminescent plat (40) sont définies par des régions non électroluminescentes (NA) entre des éléments électroluminescents plats adjacents. De premières électrodes (41) et de secondes électrodes (42) qui sont formées en exposant la première couche d'électrode et/ou la seconde couche d'électrode connectées par l'intermédiaire du substrat transparent (11) ou de l'élément d'étanchéité sont disposées dans les régions non électroluminescentes (NA) de telle manière qu'elles prennent en sandwich les lignes de coupe imaginaires (CL).
