摘要： A polarizing plate in which even slight luminance nonuniformity is provided from occurring is provided. In this polarizing plate 10, a transparent protective film 11, a polarizer 12, and an optical compensation layer 13 are laminated in this order. The moisture permeability of the transparent protective film 11 is different from that of the optical compensation layer 13. The optical compensation layer 13 is a retardation film containing at least one resin selected from norbornene resins, polyvinyl acetal resins, polyester resins, polypropylene resins, polycarbonate resins, and acrylic resins. The moisture content of the polarizing plate 10 is not more than 3%.

摘要： 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).

摘要： The present invention provides a liquid crystal panel that can provide a neutral display that is free from coloring in every direction. The liquid crystal panel includes a first polarizer 14a, a second polarizer 14b, and a liquid crystal cell 13. The first polarizer 14a is arranged on the visible side of the liquid crystal cell 13 and the second polarizer 14b is arranged on the backlight side of the liquid crystal cell 13. The liquid crystal panel further includes a first retardation layer 11 and a second retardation layer 12. A refractive index ellipsoid of the first retardation layer 11 has a relationship of nx=ny>nz, and a refractive index ellipsoid of the second retardation layer 12 has a relationship of nx>ny≧nz. The first retardation layer 11 and the second retardation layer 12 are arranged between the liquid crystal cell 13 and the second polarizer 14b.
