Abstract
Structures and methods of making wire grid polarizers having multiple regions, including side bars, strips, and/or side ribs along sides of a central region. The central region can include a single region or multiple regions. Each region can have a different function for improving polarizer performance. The various regions can support each other for improved wire grid polarizer durability.
