Abstract

시트 내부에 도부분이 2개 이상의 방사코어를 중심으로 그룹화(grouping)되어 배열된 복굴절성 해도사를 포함하는 휘도강화필름이 제공된다, 이를 통해 시트 내부에 2개 이상의 방사코어를 중심으로 도부분이 그룹화되어 배열된 복굴절성 해도사를 포함하므로 도부분과 해부분의 경계면에 광변조 계면이 형성되어 통상의 복굴절성 섬유에 비하여 광변조 효과를 극대화시킬 수 있다. 특히, 본 발명의 복굴절성 해도사는 도부분의 개수가 500개 이상이 경우에도 해도사의 중심부분에서 도부분의 뭉침현상(도접합 현상)이 발행하지 않는다. 그 결과, 방사코어가 하나인 통상의 해도사에 비하여 광변조 계면의 면적이 극대화될 수 있으므로 광변조 효과가 현저하게 상승된다. 그러므로, 통상의 시트 내부에 복굴절성 섬유나 하나의 방사코어만을 가지는 통상의 복굴절성 해도사를 사용하는 경우에 비하여 휘도가 비약적으로 향상되는 효과를 가진다.
