FINE STRUCTURE FORM AND LIQUID-CRYSTAL DISPLAY DEVICE COMPRISING FINE STRUCTURE FORM

摘要

To provide a fine structure form such as a wire-grid polarizer or an antireflection article having adequate abrasion resistance and optical properties, and a liquid crystal display device comprising such a fine structure form. A fine structure form such as a wire-grid polarizer 1 comprising a substrate having convex stripes 50 formed at a pitch of at most a visible light wavelength on at least one surface thereof, an inorganic oxide layer 30 covering at least the top 52 of the convex stripes 50, and a fluorinated compound layer 32 formed by treating at least the surface of the inorganic oxide layer 30 with a fluorinated compound having a group reactive with the inorganic oxide, wherein the inorganic oxide layer 30 covering the top 52 of the convex stripes 50 has a thickness Ha of at least 30 nm and a ratio of the thickness Ha to the width Dat (i.e. Ha/Dat) of at most 1.0; and a liquid crystal display device comprising such a fine structure form.
