Abstract

An interlayer comprising a first polymer layer, a polarization rotary optical film and optionally a second polymer layer, and multiple layer panels formed from such interlayers. The panels may exhibit desirable optical properties, including, for example, less image “ghosting,” when used as part of a heads-up-display (HUD) display panel for use in automotive and aircraft applications.
