A brightness enhancement film comprises: a high-refractive index layer having a plurality of embossed patterns provided on one surface thereof and spaced apart from each other; and a low-refractive index layer coupled to one surface of the high-refractive index layer with the embossed patterns embedded therein. Light is emitted from the high-refractive index layer toward the low-refractive index layer. Un film d'amélioration de luminosité comprend : une couche à indice de réfraction élevé ayant une pluralité de motifs gaufrés disposés sur une surface de celui-ci et espacés l'un de l'autre; et une couche à faible indice de réfraction couplée à une surface de la couche à indice de réfraction élevé avec les motifs en relief incorporés à l'intérieur de celle-ci. La lumière est émise à partir de la couche à indice de réfraction élevé vers la couche à faible indice de réfraction. 휘도 개선 필름은 일면에 다수의 양각 패턴을 이격시켜 구비하는 고굴절층과 고굴절층의 일면에서 양각 패턴을 내장하면서 결합하는 저굴절층을 포함한다. 광은 고굴절층에서 저굴절층의 방향으로 방출된다.
