LIGHT DIFFUSING PLATE, PLANAR LIGHT SOURCE DEVICE, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

Disclosed is a light diffusing plate (3) characterized in that the light diffusing plate (3) comprises a resin composition containing a propylene polymer and a light diffusing agent and satisfies the following relational formula (a) or (b): (a) 0.5 µm = D50 50 50 represents the cumulative 50% particle diameter of the light diffusing agent as measured by a Fraunhofer diffraction method using laser diffused light; and ?n represents the absolute value of the difference in refractive index between the propylene polymer and the light diffusing agent.
