Abstract
A privacy film and a display device are provided. The privacy film includes a first polarizer, a first electrode layer, a dimming liquid crystal layer, a second electrode layer, and a second polarizer. The first polarizer, the first electrode layer, the dimming liquid crystal layer, the second electrode layer, and the second polarizer are stacked in sequence, so that multi-angle privacy protection can be achieved.
