Title (EN) WAVELENGTH CONVERSION MEMBER AND BACKLIGHT UNIT
(FR) ÉLÉMENT DE CONVERSION DE LONGUEUR D’ONDE ET UNITÉ DE RÉTROÉCLAIRAGE
(JA) 波長変換部材およびバックライトユニット
Abstract:
(EN) Provided are: a wavelength conversion member which contains a phosphor such as quantum dots and has high reproducibility of white light; and a backlight unit. This wavelength conversion member comprises: a resin layer that is provided with a plurality of recesses which are discretely arranged on one main surface thereof; and a wavelength conversion layer that has a plurality of fluorescent regions containing phosphors, which are to be arranged in the recesses that are formed in the resin layer. The surface roughness Ra of a surface of the resin layer, said surface being provided with the recesses, is 0.3-5 μm.
(FR) La présente invention concerne : un élément de conversion de longueur d’onde qui contient un luminophore tel que des points quantiques et présente une reproductibilité élevée de lumière blanche ; et une unité de rétroéclairage. Cet élément de conversion de longueur d’onde comprend : une couche de résine qui est pourvue d’une pluralité d’évidements qui sont agencés de façon discrète sur une surface principale de celui-ci ; et une couche de conversion de longueur d’onde qui comporte une pluralité de régions fluorescentes contenant des luminophores, qui sont destinées à être agencés dans les évidements qui sont formés dans la couche de résine. La rugosité de surface Ra d’une surface de la couche de résine, ladite surface étant pourvue des évidements, est de 0,3 à 5 µm.
(JA) 量子ドットなどの蛍光体を含有する波長変換部材において、白色光の再現性の高い波長変換部材およびバックライトユニットを提供する。一方の主面側に離散的に配置された複数の凹部が形成された樹脂層、および、樹脂層に形成された凹部に配置される蛍光体を含む複数の蛍光領域を有する波長変換層を有し、樹脂層の凹部が形成された側の面の表面粗さRaが0.3~5μmである。
