(57) [Problem] To prevent changes in optical properties of an attached retardation plate even when a polarizing plate is stored for a long time. In a polarizing plate having a retardation plate having optical anisotropy, a first transparent protective film, a linear polarizing film, and a second transparent protective film in this order, the entire structure excluding the retardation plate from the polarizing plate is provided. The moisture permeability is less than 5 g / m 2 ยท day. |
