ABSTRACT:
A liquid crystal display includes first and second opposing substrates having first and second opposing surfaces, respectively, at least one of the surfaces having a metal disposed thereon, the substrates bonded together with an adhesive in contact with the metal, the adhesive comprising a blend of: a pressure sensitive adhesive component comprising at least one polymer having acid or base functionality, a high Tg polymer having a weight average molecular weight greater than 100,000 and having an acid or base functionality, and a crosslinker, wherein the functionality of the pressure sensitive adhesive component and the functionality of the high Tg polymer form an acid-base interaction when mixed.
