PATTERNED RETARDER LAMINATED COMPOSITE POLARIZING PLATE AND DISPLAY APPARATUS USING THE SAME

摘要

The present invention relates to a composite polarizing plate including a patterned retarder which is laminated on a polarizing plate by an adhesive layer, wherein a refractive index (N) of the adhesive layer satisfies the equation (1): min(no, ne) = N = max (no, ne) (1) wherein no represents an ordinary refractive index of the patterned retarder, ne represents an extraordinary refractive index of the patterned retarder, min(no, ne) represents the smaller between no and ne, and max(no, ne) represents the greater between no and ne, respectively. A three-dimensional display apparatus comprising the composite polarizing plate can show a uniform three-dimensional image because the moire due to difference in refractive indices between a patterned retarder and an adhesive layer can be improved. It is possible for the composite polarizing plate to provide a thinner display device since the patterned retarder can be directly laminated on the polarizing plate and a separate base film is not needed. It is also possible for the composite polarizing plate to considerably lower the possibility that foreign substances are included between layers when preparing display device including a patterned retarder and a polarizing plate.
