Un substrat (200) chevauche la surface de l'élément électroluminescent plan (100) sur le côté inverse de la surface d'exposition à la lumière. En outre, le substrat (200) a un premier motif conducteur (230) et des bornes (210, 212). Le premier motif conducteur (230) est prévu dans le but de dissiper la chaleur vers l'extérieur, ladite chaleur ayant été générée par l'unité électroluminescente (110), et chevauche 50 % ou plus de l'unité électroluminescente (110). Les bornes (210, 212) sont connectées électriquement à l'unité électroluminescente (110). Le premier motif conducteur (230) et les bornes (210, 212) sont séparés mutuellement par une distance fixe ou plus.
