Abstract
(EN)
This display device has: a substrate; a plurality of pixels that are provided to the substrate; and a plurality of red light-emitting elements and a plurality of first green light-emitting elements that are provided to each of the plurality of pixels, wherein the first green light-emitting elements light up at the same time as the red light-emitting elements, the light emission intensity of the first green light-emitting elements is less than the light emission intensity of the red light-emitting elements, and the half-value width of the spectrum of the light of the first green light-emitting elements is greater than the half-value width of the spectrum of the light of the red light-emitting elements.
(FR)
L’invention concerne un dispositif d'affichage comprenant : un substrat ; une pluralité de pixels qui sont disposés sur le substrat ; et une pluralité d'éléments électroluminescents rouges ainsi qu’une pluralité de premiers éléments électroluminescents verts qui sont disposés sur chaque pixel de la pluralité de pixels, les premiers éléments électroluminescents verts s'allumant en même temps que les éléments électroluminescents rouges, l'intensité d'émission de lumière des premiers éléments électroluminescents verts étant inférieure à l'intensité d'émission de lumière des éléments électroluminescents rouges, et la largeur de demi-valeur du spectre de la lumière des premiers éléments électroluminescents verts étant supérieure à la largeur de demi-valeur du spectre de la lumière des éléments électroluminescents rouges.
