Non-inverting transflective assembly
First Claim
1. An assembly, comprising:
- a first reflective polarizer substantially reflecting light having a first polarization state and substantially transmitting light having a second polarization state;
a polarization rotating layer positioned to receive light passing through the first reflective polarizer; and
a second reflective polarizer positioned to receive light passing through the polarization rotating layer, the second reflective polarizer substantially reflecting light having a third polarization state back through the polarization rotating layer and substantially transmitting light having a fourth polarization state.

Abstract
A film that includes a first reflective polarizer substantially reflecting light having a first polarization state and substantially transmitting light having a second polarization state, a polarization rotating layer or depolarizing layer (or both) positioned to receive light passing through the first reflective polarizer, and a second reflective polarizer positioned to receive light passing through the polarization rotating layer or depolarizing layer, the second reflective polarizer substantially reflecting light having a third polarization state back through the polarization rotating layer or depolarizing and substantially transmitting light having a fourth polarization state. Articles containing the film can be formed.
