Abstract

An optical construction includes a reflective polarizer layer having a first pass axis and an absorptive polarizer layer having a second pass axis that is substantially aligned with the first pass axis. At least one electrically conductive light scattering layer is arranged between the reflective polarizer layer and the absorptive polarizer layer.
