High‐contrast, thin‐film polarizers based on dye‐doped reactive liquid crystals (see figure) equal the polarization performance of conventional sheet polarizers at strongly reduced thicknesses. Advantageously, the guest–host polarizers can be patterned and applications are envisioned in liquid‐crystal displays.
