Abstract
The invention generally relates to polymer films used as protective cover sheets for polarizer plates, a method for producing polarizing plates, and a Liquid Crystal Display employing the same. More particularly, the invention relates to cover sheet composites having a removable, carrier substrate and, optionally, a strippable, protection layer that protects the cover sheet from abrasion and dirt during the manufacture of the cover sheet and polarizer plates.
