Abstract
(EN)
Provided is a display device which can suppress deterioration of color purity. The display device is provided with: a first resonator structure having an upper reflecting member, a lower reflecting member and a light emitting functional layer which is arranged between the upper reflecting member and the lower reflecting member and includes a red light emitting layer that emits red light; a second resonator structure having an upper reflecting member, a lower reflecting member and a light emitting functional layer which is arranged between the upper reflecting member and the lower reflecting member and includes a blue light emitting layer that emits blue light; a third resonator structure having an upper reflecting member, a lower reflecting member and a light emitting functional layer which is arranged between the upper reflecting member and the lower reflecting member and includes a green light emitting layer that emits green light.  The red light emitting layer is a common layer arranged for each light emitting functional layer of the first to third resonator structures.

L'invention concerne un dispositif d'affichage capable de limiter la dégradation de la pureté des couleurs. Le dispositif d'affichage comporte : une première structure de résonateur dotée d'un élément réfléchissant supérieur, d'un élément réfléchissant inférieur et d'une couche fonctionnelle électroluminescente qui est placée entre l'élément réfléchissant supérieur et l'élément réfléchissant inférieur et qui comprend une couche électroluminescente rouge émettant une lumière rouge ; une deuxième structure de résonateur dotée d'un élément réfléchissant supérieur, d'un élément réfléchissant inférieur et d'une couche fonctionnelle électroluminescente qui est placée entre l'élément réfléchissant supérieur et l'élément réfléchissant inférieur et qui comprend une couche électroluminescente bleue émettant une lumière bleue ; une troisième structure de résonateur dotée d'un élément réfléchissant supérieur, d'un élément réfléchissant inférieur et d'une couche fonctionnelle électroluminescente qui est placée entre l'élément réfléchissant supérieur et l'élément réfléchissant inférieur et qui comprend une couche électroluminescente verte émettant une lumière verte. La couche électroluminescente rouge est une couche commune mise en place pour chaque couche fonctionnelle électroluminescente de la première à la troisième structure de résonateur.
