OPTICAL MEMBER, POLARIZING PLATE SET, AND LIQUID CRYSTAL DISPLAY DEVICE

Title:

OPTICAL MEMBER, POLARIZING PLATE SET, AND LIQUID CRYSTAL DISPLAY DEVICE

Document Type and Number:

WIPO Patent Application WO/2014/042110

Kind Code:

A1

Abstract:

Provided is an optical member that can achieve a liquid crystal display device having high brightness, superior mechanical strength, and a suppressed occurrence of moiré and glare. The optical member includes a polarizing plate, a light-diffusing adhesive layer, a reflecting polarizer, and a prism sheet. The volume-average particle size of light-diffusing microparticles contained in the light-diffusing adhesive layer is 1-4 μm, and the refractive index of the adhesive is at least 1.47. Preferably, the haze value of the light-diffusing adhesive layer is 80-95%.
