Document Type and Number:
WIPO Patent Application WO/2013/108563
Kind Code:
A1
Abstract:
A new reflector which effectively prevents brightness inconsistency by having a diffuse reflector with high diffusivity, is provided as an outermost layer equipped with a surface used for reflection. A reflector which has a resin layer (A) with a diffuse reflector, wherein the standard deviation (σ,δ (n)) of plane angle is 8.0 or more, is proposed as an outermost layer equipped with a surface used for reflection. Further, a reflector is proposed, wherein said resin layer (A) is preferably constituted by a mixture of two or more thermoplastic resins having an absolute value of the difference between solubility parameters (SP values), which is 0.3 to 3.0 (cal/cm3)0.5.
