| titleOfInvention | Circular polarizing plate, display device and laminated retardation plate |
| abstract | The present invention provides a circular polarizing plate and a laminated retardation plate which can be thinned and have both a wide frequency band and a wide viewing angle, and a display device having the circular polarizing plate. A circular polarizing plate having: a first retardation layer showing negative refractive index anisotropy, a second retardation layer showing positive refractive index anisotropy, and a linear polarizing element, the optical axis of the first retardation layer Parallel to the optical axis of the second retardation layer, the absolute value of the in-plane retardation of the first retardation layer for light with a wavelength of λnm is defined as |R1(λ)|, and the second retardation layer is When the absolute value of the in-plane retardation of light having a wavelength of λnm is defined as |R2(λ)|, the following equations (1) to (4) are satisfied. |R1(450)|>|R1(550)|>|R1(650)| (1),|R2(550)|>|R1(550)| (2),|R2(550)|‑|R1 (550)|>|R2(450)|‑|R1(450)| (3),|R2(650)|‑|R1(650)|>|R2(550)|‑|R1(550)|( 4). |
