  • Publication number: 20240111082
    Abstract: Provided are a polarizing plate for antireflection including a polarizer, and a protective layer formed on at least one surface of the polarizer, wherein the polarizing plate has a single transmittance of 44.6% or more and a degree of polarization of 98% or more and satisfies 0?[(orthogonal a*)2+(orthogonal b*)2]0.5?16, and a display device including the polarizing plate. The polarizing plate for antireflection can exhibit high transmittance while preventing blue-shift phenomenon and having neutral reflection color. Further, the polarizing plate for antireflection can be made thinner.
    Type: Application

  • Publication number: 20220057560
    Abstract: Provided are a polarizing plate for antireflection containing a polarizer, and a protective layer formed on at least one surface of the polarizer, wherein the polarizing plate has a single transmittance of 44.6% or more and a degree of polarization of 98% or more, and a dispersion in width direction of an absorption axis of the polarizer is 0.04° or less when a stretching direction of the polarizer is set to 0°, and a display device containing the polarizing plate. The polarizing plate for antireflection can minimize dispersion of optical performance and prevent the polarizer from being cut off during a preparation process while exhibiting high transmittance. Further, the polarizing plate for antireflection can be made thinner.
