Abstract
A polarizing plate having excellent moisture durability and a liquid crystal display using the same are disclosed. The polarizing plate is produced by covering all surfaces and sides of a polarizer with low moisture-permeable layers having moisture permeability of 310 g/m2·24 h or less. The rate of change in dimension of the polarizer in the uniaxially stretched direction is ±0.1% or less after left at a temperature of 60° C. and humidity of 95% for 100 hours.

A polarizing plate comprising a polarizer, wherein all surfaces and sides of the polarizer are covered with low moisture-permeable layers having moisture permeability of 310 g/m2·24 h or less.
A liquid crystal display comprising:
- a liquid crystal cell having a first side and a second side;
- and a polarizer having all surfaces and sides covered with low moisture-permeable layers having moisture permeability of 310 g/m2·24 h or less;
- the polarizer attached to at least one side of the liquid crystal cell.
