OPTICAL MEMBER AND DISPLAY DEVICE

Document Type and Number:

WIPO Patent Application WO/2015/076409

Kind Code:

A1

Abstract:

　This optical member has: a phase-difference layer (32) that has a plurality of first regions (32a) for changing an incident linearly polarized light to a first polarization state and a plurality of second regions (32b) for making a change to a second polarization state, the first regions (32a) and the second regions (32b) being disposed in a prescribed pattern in plan view; a polarizer layer (2) provided on one side of the phase difference layer (32); and an anti-glare layer provided on the surface of the other side of the phase-difference layer (32). The arithmetic mean height (Pa) of the concavo-convex surface of the anti-glare layer on an arbitrary cross-section curve is 0.15 μm or less, and the maximum cross-section height (Pt) is 1.5 μm or less.
