A tunable electro‐optical switching is reported for single‐layered polymer‐dispersed liquid crystal (PDLC) films, controlled by the film thickness. Thin planar film of two‐dimensional layer of thickness continuously varying from a few micrometers to several tens of micrometers is examined. The wedge‐confined PDLC single layer contains E7 liquid‐crystal microdroplets dispersed in a transparent polymer matrix of NOA65. The diameters of the droplets with a linear‐gradient size distribution along the wedge slope reach several tens of micrometers, defined by the wedge geometry of the film. The electro‐optical switching of the single‐layered PDLC film is linked to its microstructure and droplet organization.
