1. Technical Field
Embodiments of the present invention relate to an adhesive composition for polarizing plates, a polarizing plate including the same, and an optical display including the same.
2. Description of the Related Art
A liquid crystal display includes a liquid crystal display panel and polarizing plates formed on both surfaces of the liquid crystal display panel. The polarizing plates may be stacked on the liquid crystal display panel via adhesive films for polarizing plates. Each of the adhesive films may be formed by coating an adhesive composition for polarizing plates onto one surface of the polarizing plate or a release film, followed by aging for a predetermined period of time.
The adhesive composition for polarizing plates is generally aged in an aging chamber for 3 to 7 days, or for 10 days or longer, as needed. As such, aging costs time and money. If the adhesive composition for polarizing plates is not subjected to sufficient aging, however, the properties of the adhesive film are poor (such as poor creep characteristics, peel strength, reliability, light leakage and reworkability), and the adhesive film therefore cannot be used in a polarizing plate. In addition, if the aging time is reduced, the adhesive composition can have poor pot-life, thereby causing poor coatability.
