Abstract
The present invention provides a polarizing plate that includes: a transparent protective film; a polarizer; and an optical compensation layer. The transparent protective film, the polarizer, and the optical compensation layer are laminated in this order. A moisture percentage of the polarizing plate is 2.8% by mass or less. The optical compensation layer includes a retardation film. The retardation film includes at least one resin selected from the group consisting of norbornene resins, cellulose resins, polyvinyl acetal resins, polyimide resins, polyester resins, and polycarbonate resins. The optical compensation layer shows an optical property represented by the following formula (I):nx>ny>nz (I).
