<p>In a diffusion sheet (46), first reflection areas (AR1) with high reflectance and second reflection areas (AR2) with low reflectance are alternately arranged parallel to each other on a light receiving surface (46R), and third reflection areas (AR3) with high reflectance and fourth reflection areas (AR4) with low reflectance are alternately arranged parallel to each other on an light emitting surface (46F). In the diffusion sheet (46), the first reflection areas (AR1) and the fourth reflection areas (AR4) are opposed to each other, and the second reflection areas (AR2) and the third reflection areas (AR3) are opposed to each other.</p> |
