Abstract
A reflective polarizer suitable for use in a display device is disclosed herein. The reflective polarizer includes: a multilayer optical film including alternating layers of first and second polymeric layers that reflects light of a first polarization state and transmits light of a second polarization state, wherein for normally incident light of the second polarization state, the reflective polarizer has an internal percent transmission of at least 95% at 410 nm, and at most 25% at 380 nm. Also disclosed herein is a display device including the reflective polarizer.
