Patent ID: 8434885

Claim:
A reflecting sheet comprised of at least two, a surface layer portion and an inner layer portion, or more layers, wherein the surface layer portion contains at least a thermoplastic resin (C), the inner layer portion contains a thermoplastic resin (A), and at least one kind of thermoplastic resin (B) incompatible with the thermoplastic resin (A), wherein reflected light intensity in a vertical direction has anisotropy by an incident direction when light is incident at an incident angle of 60 degrees with respect to the vertical direction of a plane of the reflecting sheet in the entire reflecting sheet including the surface layer portion and the inner layer portion, and wherein a ratio L 1 /L 2 is 1.2 or more, the ratio being a ratio of reflected light intensity L 1 in the vertical direction in an incident direction A 1 where the reflected light intensity in the vertical direction is the highest to reflected light intensity L 2 in the vertical direction in an incident direction A 2 orthogonal to the incident direction A 1 .
