PRESSURE-SENSITIVE ADHESIVE COMPOSITION, OPTICAL FILTER AND PLASMA DISPLAY PANEL DISPLAY DEVICE USING THE SAME

摘要

The present invention relates to a pressure-sensitive adhesive composition for optical filter used in Plasma Display Panel (PDP), a pressure-sensitive adhesive film, an optical filter and a PDP panel display device, using the same. More specifically, the present invention relates to a pressure-sensitive adhesive composition having a dynamic storage elastic modulus of 5 x 10³ ~ 5 x 10⁴ Pa and a dynamic loss elastic modulus of 5 x 10² ~ 5 x 10³ Pa, at a temperature of 3O⁰C and a frequency of 0.01 Hz, and a dynamic storage elastic modulus of 8 x l0 ³ ~ l x l0⁵ Pa and a dynamic loss elastic modulus of l x l0 ³ ~ 5 x l0⁴ Pa, at a temperature of 3O⁰C and a frequency of 500 Hz. The pressure-sensitive adhesive according to the present invention and the optical filter applied by the adhesive comply with endurance reliability under high temperature/high humidity conditions, do not cause fine bubbles on bonding the optical filter directly to PDP and have excellent re-workability in adhering processes.
