Title:
LIQUID CRYSTAL DISPLAY DEVICE AND MULTILAYER OPTICAL MEMBER
Document Type and Number:
WIPO Patent Application WO/2012/002183
Kind Code:
A1
Abstract:
Disclosed is a liquid crystal display device (1) which comprises: a light-diffusing optical member (3); a light source device (50) that is arranged on the back surface side of the light-diffusing optical member (3); a VA liquid crystal panel (30) that is arranged on the front surface side of the light-diffusing optical member (3); and a reflective polarization splitting film (40) that is arranged between the light-diffusing optical member (3) and the VA liquid crystal panel (30). The light-diffusing optical member (3) comprises a transparent material and light diffusion particles that are dispersed in the transparent material. If the absolute value of the difference between the refractive index of the transparent material and the refractive index of the light diffusion particles is represented by ∆n and the cumulative 50% particle diameter of the light diffusion particles is represented by D50 (μm), the relation 0.01 ≤ ∆n × D50 ≤ 0.25 is satisfied.
