Abstract

A polarizing plate includes a first glass plate; a second glass plate facing the first glass plate; and a polarizing device between the first and second glass plates. An external surface of at least one of the first and second glass plates, which is not in contact with the polarizing device, has a root mean square surface roughness of about 1 nanometer or less.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A polarizing plate, comprising:
 a first protective film;   a second protective film facing the first protective film; and   a polarizing device between the first and second protective films,   wherein   the first protective film comprises glass,   the second protective film comprises a copolymer film, and   an external surface of the first protective film, which is not in contact with the polarizing device, has a root mean square surface roughness of about 1 nanometer or less.   
     
     
         2 . The polarizing plate of  claim 1 , wherein the polarizing device comprises a resin comprising polyvinyl alcohol containing a dichroic material. 
     
     
         3 . The polarizing plate of  claim 1 , wherein the first protective film has a thickness of about 1 micrometer to about 500 micrometers.
