Summary: | To provide a light reflection sheet which exhibits high light guide property and has good productivity even when being stuck to a light guide plate and used, in a surface light source device such as a liquid crystal display.SOLUTION: A light reflection sheet has a low refractive index layer 2 having a reflective index of 1.35 or less and a resin layer 3 which does not substantially contain inorganic particles, in which the low refractive index layer 2 and the resin layer 3 are brought into contact with each other, the resin layer 1 contains a polyester resin, and the low refractive index layer 2 contains hollow particles and has a thickness of 10-1,000 nm.SELECTED DRAWING: Figure 1
【課題】液晶ディスプレイなどの面光源装置において、導光板と貼り合わせて用いられた場合でも、高い導光性を示し、また生産性の良い光反射シートを提供する。【解決手段】屈折率が1.35以下の低屈折率層2と無機粒子を実質的に含有しない樹脂層3を有し、前記低屈折率層2と前記樹脂層3が接し、前記樹脂層1がポリエステル樹脂を含み、前記低屈折率層2が中空粒子を含有して、その厚みが10〜1000nmであることを特徴とする。【選択図】図1 |
