Abstract: Provided is a polarizing plate having a wire grid structure, comprising a transparent substrate, a first antireflection film laminated on the first surface of the transparent substrate, a plurality of protrusions protruding from the first antireflection film, a second antireflection layer laminated on a second surface opposite to the first surface, wherein the plurality of protrusions are periodically arranged at a pitch shorter than a wavelength of light in a use band, each of the protrusions extends in in a first direction and includes a reflective layer, a dielectric layer, and an absorption layer in order from the first direction, and both the first antireflection layer and the second antireflection layer have high refractive index layers and low refractive index layers that are alternately laminated.

Abstract: A simple, easy to manufacture, replacement zipper pull for zippers and slide fasteners suitable for mounting and safely displaying cabochons and jewels is described where a solid blank body with a display surface for mounting a cabochon or jewel, has an open hexahedral slot, drilled, routed, molded and/or cast, penetrating into the blank body beneath the display surface, and where transverse passageway is created within the blank body having a width greater than that of the slot for establishing a base-end of the slot and creating an anchor hole in each side of the slot for receiving outward extending distal tips of legs of a U-shaped, spring wire bail sized for insertion into the hexahedral slot, where the distal tips of the legs of the U-shaped spring bail span outward to a width greater than the width of the hexahedral slot, and snap into the created anchor holes at the base-end of the slot, for securing the blank body to the loop tang atop a zipper or slider fastener through which the U-shaped spring bail
