Title:
LIGHT DIFFUSING PLATE, SURFACE LIGHT-EMITTING DEVICE, AND LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/209254
Kind Code:
A1
Abstract:
Provided is a light diffusing plate that diffuses and transmits light from a plurality of light sources from one to the other of two main surfaces facing each other, wherein: letting, when light with a wavelength of 550 nm is made orthogonally incident to the one main surface, Tt be total light ray transmittance, I0 be the intensity of transmitted light when the output direction is identical to the direction of incidence, and I30 be the intensity of transmitted light for an output direction that is a direction at an inclination of 30° to the direction of incidence, Tt is 10 - 70% and I30/I0 is 0.6 or greater; and the light diffusion plate is formed from glass such that the specific elastic modulus is at least 26.0 GPa∙cm3/g, and in the mol% content for the oxide basis, MgO is 1 - 16%, P2O5 0 - 5%, and Al2O3 1 - 9%.
