In article number 1908592, Young Min Song and co‐workers develop a flexible, large‐area covert polarization display based on ultra‐thin lossy nanocolumns with a wide color selectivity. Multi‐functional covert polarization display labels are attached to daily objects with curved and wrinkled surfaces, and hidden quick response codes are revealed by polarization adjustment or water contact.
