Provided is a luminance improving film, which includes a high refractive index layer having a plurality of embossed patterns spaced apart on one surface and a low refractive index layer coupled while embedding embossed patterns on one surface of the high refractive index layer. Light is emitted from the high refractive index layer to the low refractive index layer. According to the present invention, front luminance and omnidirectional luminance can be increased. 휘도 개선 필름은 일면에 다수의 양각 패턴을 이격시켜 구비하는 고굴절층과 고굴절층의 일면에서 양각 패턴을 내장하면서 결합하는 저굴절층을 포함한다. 광은 고굴절층에서 저굴절층의 방향으로 방출된다.
