Abstract: Disclosed are an anti-peeping film and a display device. In the present disclosure, an angle between long axes of liquid crystal molecules in a liquid crystal light-adjusting layer and planes in which polarizers are located is set to be an acute angle in a first mode, so that there is an angle between effective long axes of the liquid crystal molecules in the liquid crystal light-adjusting layer and a direction of polarized light in a side-view direction. Therefore, light in the side-view direction of the anti-peeping film is darker. Thus, an anti-peeping effect can be realized, while sharing can be realized in a non-first mode.

Abstract: A display device and a dimming device are provided. A dimming layer is located between a first polarizer and a second polarizer whose transmission axes are parallel to each other. When the display device is in a first display mode, long axes of the liquid crystal molecules distributed in the first polymer network are arranged along the second direction, and long axis of the liquid crystal molecules distributed in the second polymer network are arranged along the third direction. The third direction and the second direction respectively point to opposite sides of a normal line of the first polarizer.

Abstract: This application discloses a display panel and a manufacturing method thereof, and a display device. A light-adjusting liquid crystal cell of the display panel includes a first substrate, a second substrate, a light-adjusting liquid crystal layer and a sealing layer. The ultraviolet light transmittance of the first substrate in a display area is less than a predetermined threshold, and the ultraviolet light transmittance of the second substrate in the display area is greater than or equal to the predetermined threshold. During the curing of frame glue, it can prevent pre-polymerized molecules from being exposed to light in advance. During the curing of the pre-polymerized molecules, it can make the pre-polymerized molecules have a cross-linking reaction to form a polymer network.
