Patent ID: 11054691

Abstract:
The present invention provides a polarizing plate including a polarizer having a high transmittance, which can be suitably applied to a circularly polarizing plate with which a significant decrease in an antireflection ability is suppressed in a case where the circularly polarizing plate is disposed on a display element; a circularly polarizing plate; and a display device. The polarizing plate includes a polarizer and an adjacent layer in contact with the polarizer, in which a transmittance in the absorption axis direction of the polarizer is 4.0% or more, and an in-plane average refractive index of the adjacent layer satisfies a relationship of Formula (X), Formula (X): Refractive index in a transmission axis direction of the polarizer<In-plane average refractive index of the adjacent layer<Refractive index in the absorption axis direction of the polarizer.
