ANISOTROPIC LIGHT DIFFUSION ADHESIVE LAYER, ANISOTROPIC LIGHT DIFFUSION ADHESIVE LAMINATED ASSEMBLY, AND ILLUMINATION DEVICE INCORPORATING ANISOTROPIC LIGHT DIFFUSION ADHESIVE LAMINATED ASSEMBLY

摘要

Pressure-sensitive adhesive, said pressure-sensitive adhesive and the refractive index is dispersed and at the same time containing the other oriented needle-like filler is needle-like filler in the substantially same direction as the anisotropic light-diffusing adhesive layers. The needle-like filler is preferably colorless or white. The multiple overlap to bond the anisotropic light-diffusing adhesive layer may be formed of the anisotropic light-diffusing pressure-sensitive adhesive laminate. The anisotropic light-diffusing pressure-sensitive adhesive layer and the anisotropic light-diffusing laminate of the adhesive may be suitably used as a lighting device such as a backlight of a liquid crystal display device. ; The anisotropic light-diffusing pressure-sensitive adhesive layer, the anisotropic light-diffusing laminate of the adhesive, the illumination device, needle-shaped filler, a liquid crystal display backlight
