摘要： A polarizing plate has a polarizer and a protective film formed on at least one surface of the polarizer. The protective film is formed by curing an energy ray-curable composition that contains at least one of a first energy ray-polymerizing compound having a bisphenol residue, a second energy ray-polymerizing compound having a neopentylglycol group, a third energy ray-polymerizing compound having a trimethylolpropane group, and a fourth energy ray-polymerizing compound having a pentaerythritol group. In the polarizing plate, though the protective film is thin, the polarizer is protected from the influence of external moisture, etc., and therefore its polarizability is kept good even in high-temperature high-humidity environments.

摘要： A polarizing plate is provided in which adhesion properties between a polarizer and a protection film are improved and in which the optical properties of the polarizer are stable under the influence of moisture and the like. Specifically, in polarizing plates 4 and 12, protection films 3 and 11 are formed on at least one side of polarizers 2 and 10, respectively, by curing an energy ray-curable composition. The energy ray-curable composition contains (1) an energy ray-polymerizable compound having a bridged hydrocarbon group, a bisphenol group, a neopentyl glycol group, a trimethylolpropane group, or a pentaerythritol group and (2) a hydrolysate of a silane-based coupling agent. At least one of the polarizing plates 4 and 12 is provided on at least one side of a liquid crystal panel 1, whereby a liquid crystal device 9 is constituted.
