  • Reflection sheets
    Publication number: 20070229992
    Abstract: A reflection sheet includes a transparent substrate, a directional reflection layer formed on a first surface of the transparent substrate, and a shield reflection layer formed on the directional reflection layer. As light enters into the transparent substrate from a second surface of the transparent substrate, a first portion of the light is mirror reflected via the directional reflection layer to leave the transparent substrate, and a second portion of the light passing through the directional reflection layer leaves the transparent substrate due to shielding and reflecting of the shield reflection layer.
