Abstract
A privacy filter, a display panel, and a display device are provided. The display panel includes a panel body, and a first polarizer, a dimming liquid crystal layer, and a second polarizer that are sequentially disposed on one side of the panel body. The dimming liquid crystal layer includes a plurality of polymer networks and a plurality of liquid crystal molecules distributed in the polymer networks, wherein the plurality of polymer networks are arranged in a first direction, the first direction tilts relative to a normal direction of the first polarizer, and an optical axis direction of the first polarizer is parallel to an optical axis direction of the second polarizer.
