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.

A privacy film, comprising:
- a first polarizer;
- a first electrode layer;
- a dimming liquid crystal layer;
- a second electrode layer;
- and
- a second polarizer, wherein the first polarizer, the first electrode layer, the dimming liquid crystal layer, the second electrode layer, and the second polarizer are stacked in sequence;
