Abstract
The present disclosure provides a reflective polarizer including a plurality of polymeric first layers and a plurality of polymeric second layers. A plot of an average layer thickness versus a layer number for the pluralities of polymeric first, but not second, layers includes a knee region separating a left region including at least 50 sequentially arranged polymeric first layers. The polymeric first layers have lower layer numbers, and the average layer thickness increases with increasing layer number from a right region including at least 5 sequentially arranged polymeric first layers. The polymeric first layers have higher layer numbers and the average thickness increases with increasing layer number, such that linear fits to the at least 50 sequentially arranged polymeric first layers and to the at least 5 sequentially arranged polymeric first layers have respective positive slopes S1 and S2, S2/S1≥5.
