LAMINATED POLARIZING PLATE AND DISPLAY DEVICE |
摘要 |
PROBLEM TO BE SOLVED: To provide a laminated polarizing plate that can be made thinner and achieve superior viewing angle characteristics.SOLUTION: A laminated polarizing plate 11 includes a polarizer 12, a first optical anisotropic layer 13, and a second optical anisotropic layer 14. The first optical anisotropic layer 13 is formed of a film comprising an organic polymer and at least one type of dichroic dye. The first optical anisotropic layer 13 has such retardation characteristics that an in-plane retardation value Re1a of the first optical anisotropic layer 13 and an in-plane retardation value Re1b of the first optical anisotropic layer 13 of a film similar to the above film excluding the dichroic dye satisfy expression (1) Re1a(580)/Re1a(550)-Re1b(580)/Re1b(550)>0. The second optical anisotropic layer 14 has refractive index characteristics represented by ny2≤nx2<nz2.SELECTED DRAWING: Figure 3 |
