摘要： This invention relates to a filter for a plasma display panel having excellent re-workability, durability, and reliability and a plasma display panel including the same. The filter for a plasma display panel of this invention is characterized by including an acrylic pressure-sensitive adhesive composition layer having adhesion after the lapse of a predetermined time period that is at least 1.5 times as great as initial adhesion. Since the inventive filter for a plasma display panel has low initial adhesion, when a defect occurs in a process of attaching the filter for a plasma display panel to an upper glass plate of the panel, a separation process may be easily conducted, and also adhesion increases with the lapse of time, thus exhibiting good durability and reliability without air bubbling and peeling.
