Title (EN) LIGHT CONVERSION MEMBER
(FR) ÉLÉMENT DE CONVERSION DE LUMIÈRE
(JA) 光変換部材
Abstract:
(EN) The present invention provides a light conversion member that creates a high output luminance even with a barrier layer present. Specifically, the light conversion member comprises: a light conversion film for converting light from a prescribed color; a first gas barrier part positioned near the surface onto which the light to be converted by the light conversion film is incident and made up of one or more gas barrier layers protecting the light conversion film from the entry of moisture and gas; and a first base material positioned at the surface of the first gas barrier part opposite the surface whereon the light conversion film is positioned, transmitting light, and retaining the light conversion film and the first gas barrier part. The first gas barrier part is characterized in that the light transmittance of the combination of the first base material and the first gas barrier part is higher than the light transmittance of the first base material with respect to the light having a prescribed color.
(FR) L'invention se rapporte à un élément de conversion de lumière qui crée une luminance à rendement élevé même avec une couche barrière présente. Plus particulièrement, l'élément de conversion de lumière comprend : un film de conversion de lumière qui permet de convertir une lumière à partir d'une couleur imposée ; une première partie barrière contre les gaz qui est positionnée à proximité de la surface sur laquelle arrive la lumière devant être convertie par le film de conversion de lumière, et qui est constituée d'une ou plusieurs couches barrières contre les gaz protégeant ce film de conversion de lumière de l'entrée de l'humidité et des gaz ; et un premier matériau de base qui est positionné à l'emplacement de la surface de la première partie barrière contre les gaz en regard de la surface sur laquelle le film de conversion de lumière est positionné, qui transmet la lumière, et qui retient ledit film de conversion de lumière et ladite première partie barrière contre les gaz. Cette première partie barrière contre les gaz est caractérisée en ce que la transmittance de la combinaison du premier matériau de base et de la première partie barrière contre les gaz est supérieure à la transmittance du premier matériau de base par rapport à la lumière ayant une couleur imposée.
(JA) バリア層を形成しても、高い出力輝度を得ることができる光変換部材を提供する。具体的には、光の色を所定の色から変換する光変換膜と、光変換膜の変換する光が入射する面側に位置し、光変換膜への水分、ガスの浸入を防ぐ一層以上のガスバリア層からなる第1のガスバリア部と、第1のガスバリア部の光変換膜が位置する面と反対面側に位置し、光を透過し、光変換膜および第1のガスバリア部を保持する第1の基材と、を有し、所定の色の光に対して、第1の基材の光透過率よりも、第1の基材と第1のガスバリア部の両方を組み合わせた物の光透過率の方が高い特徴を持つ第1のガスバリア部を備えている。
