OPTICAL MEMBER, DISPLAY ILLUMINATING DEVICE, DISPLAY AND TELEVISION RECEIVER

摘要

An optical member (15) is provided with a lens sheet (28) wherein a plurality of convex lenses (29) are arranged within the surface; a light diffusion sheet (27) arranged to face the lens sheet (28) to diffuse light; and a light reflecting member (24), which is formed between the lens sheet (28) and the light diffusion sheet (27) and is selectively arranged on each of the boundaries between the convex lenses (29). The lens sheet (28) has a light collecting direction within the lens sheet (28) and a non light collecting direction which intersects with the light collecting direction, as the convex lens (29) has anisotropy in collecting light. The light diffusion sheet (27) has higher diffuseness in the light collecting direction of the lens sheet (28) than in the non light collecting direction of the lens sheet (28).
