Abstract
A polarizer stack including an absorbing polarizer and a multilayer polymeric reflective polarizer bonded together is described. The absorbing polarizer has a first block axis and the reflective polarizer has a second block axis substantially parallel to the first block axis. The reflective polarizer may be substantially free of micro-wrinkling when the polarizer stack adhered to a glass layer is heated at 95° C. for 100 hours.
