More Information
Summary:Provided are a laminate polarization plate with excellent viewing angle properties and excellent visibility especially in diagonal directions, and an organic EL element using said laminate polarization plate; this laminate polarization plate is formed by laminating at least a polarizer, a first optically anisotropic layer and a second optically anisotropic layer in that order, and fulfils [1] below, and this organic EL element uses this laminate polarization plate. [1] -40nm ≤ Rth1+Rth2 ≤ 40nm (here, Rth1 is the retardation value in the thickness direction of the first optically anisotropic layer and Rth2 is the retardation value in the thickness direction of the second optically anisotropic layer.)
