Abstract
(EN)
This color conversion substrate is characterized by having a partition wall on a substrate and having, in a region partitioned by the partition wall, a green color conversion layer, a red color conversion layer, and a non-color conversion layer not including a phosphor, wherein the green color conversion layer and the red color conversion layer include light-emitting materials, and when Sg is the area of the green color conversion layer, Sr is the area of the red color conversion layer, and Sn is the area of the non-color conversion layer, Sg, Sr, and Sn satisfy the relationship of the following expressions (A) and (B). (A): Sn < Sg, (B): Sn < Sr
(FR)
L'invention concerne un substrat de conversion de couleur qui est caractérisé en ce qu'il comporte une paroi de séparation sur un substrat et ayant, dans une région divisée par la paroi de séparation, une couche de conversion de couleur verte, une couche de conversion de couleur rouge, et une couche de conversion non colorée ne comprenant pas de phosphore, la couche de conversion de couleur verte et la couche de conversion de couleur rouge comprenant des matériaux électroluminescents, et lorsque Sg est la zone de la couche de conversion de couleur verte, Sr est la zone de la couche de conversion de couleur rouge, et Sn est la surface de la couche de conversion non colorée, Sg, Sr et Sn satisfont la relation des expressions suivantes (A) et (B). (A) : Sn < Sg, (B) : Sn < Sr
(JA)
基板上に隔壁を有し、かつ隔壁により仕切られた領域に緑色色変換層と、赤色色変換層と、蛍光体を含まない非色変換層とを有する色変換基板であって、前記緑色色変換層および赤色色変換層は発光材料を含み、かつ前記緑色色変換層の面積をSg、前記赤色色変換層の面積をSr、前記非色変換層の面積をSnとしたとき、Sg、Sr、Snが以下の式(A)および式(B)の関係を満たすことを特徴とする色変換基板。 式(A) Sn<Sg 式(B) Sn<Sr
