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.

Novel membranes comprising various polymers containing heterocyclic nitrogen groups are described. These membranes are usefully employed in electrochemical sensors, such as amperometric biosensors. More particularly, these membranes effectively regulate a flux of analyte to a measurement electrode in an electrochemical sensor, thereby improving the functioning of the electrochemical sensor over a significant range of analyte concentrations. Electrochemical sensors equipped with such membranes are also described.

摘要:
An LED having vertical topology and a method of making the same is capable of improving a luminous efficiency and reliability, and is also capable of achieving mass productivity. The method includes forming a semiconductor layer on a substrate; forming a first electrode on the semiconductor layer; forming a supporting layer on the first electrode; generating an acoustic stress wave at the interface between the substrate and semiconductor layer, thereby separating the substrate from the semiconductor layer; and forming a second electrode on the semiconductor layer exposed by the separation of the substrate.
