A pressure-sensitive adhesive composition for PDP front filters includes 100 parts by weight of a high molecular weight acrylic polymer A having a COOH or OH group, a weight average molecular weight (Mw) of 400,000 to less than 800,000, a molecular weight distribution (Mw/Mn) of not more than 5 and a glass transition temperature (Tg-A) of −40 to −10° C., and 5 to 20 parts by weight of a low molecular weight acrylic polymer B having a weight average molecular weight (Mw) of 10,000 to 50,000, a molecular weight distribution (Mw/Mn) of not more than 5 and a glass transition temperature (Tg-B) of 40 to 120° C.; and is crosslinked to a gel fraction of 50 to 90% and has a 90° peel strength of 5 to 15 N/25 mm. The pressure-sensitive adhesive composition does not cause bonding failures such as lifting even when exposed to thermal cycles. |
