POLARIZER FILMS AND METHODS OF MAKING THE SAME

摘要

In general, in one aspect, the invention features an article that includes a layer including a plurality of spaced-apart portions of a first material extending along a first direction. The layer transmits about 20% or more of light of wavelength ? having a first polarization state incident on the layer along a path. The layer transmits about 2% or less of light of wavelength having a second polarization state incident on the layer along the path, the first and second polarization states being orthogonal. For wavelength ?, the first material has a refractive index of 1.8 or more and an extinction coefficient of 1.8 or more, and ? is 300 nm or less.
