Title:
POLARIZING PLATE AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2003302532
Kind Code:
A
Abstract:
To provide a polarizing plate which shows the effect of improving transmittance without depending on wavelengths and to provide a method for manufacturing the plate.
The polarizing plate has a moth-eye structure on the surface of at least one layer. Preferably, the surface having the moth-eye structure satisfies the relation of 0.001 μm<Ra(3)<5.0 μm, 0.001 μm<RSm(3)<0.5 μm, and 0.01<Ra(3)/RSm(3)<5.0, wherein Ra(3) is the arithmetical mean height of the profile and RSm(3) is the mean length of the profile element defined by JISB 06012001.
