Free‐space volumetric displays is a three‐dimensional (3D) display technology without the needs of polarizer or shutter glasses for direct view or a screen for image projection. Here we present a volumetric display using a stack of active cholesteric diffusers. This display works by integrate each individual image and scans through a stacked active diffusers prepared by the reverse‐mode polymer‐stabilized cholesteric texture (R‐PSCT), which have high optical contrast and fast switching characteristics.
