A device which simultaneously maximizes light reflectivity from one side of the device while maximizing light transmissivity from the opposite side of the device. The device is configured with distinct regions of transparency and reflectivity including a plurality of reflective structures. The structures are generally smaller towards a light transmitting side of the device and larger towards a light reflective side of the device.
