Abstract: Disclosed is a display device including a display panel, a reflective polarizing layer, a liquid crystal dimmer cell, and a first polarizing plate which are sequentially stacked, wherein a reflection surface of the reflective polarizing layer faces the liquid crystal dimmer cell, and a direction of a transmission axis of the reflective polarizing layer is same as a direction of a transmission axis of the first polarizing plate, so that not only a peep-proof function of the display device can be realized, but also ambient light with a large viewing angle can be reflected, which can further reduce the visibility of the display screen under the large viewing angle without affecting the display at the front viewing angle.

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: A privacy film and a display device are provided. The privacy film comprises a liquid crystal dimming cell and a first polarizer. The liquid crystal dimming cell comprises two opposed substrates and a liquid crystal layer sandwiched between the two substrates. The liquid crystal layer comprises a plurality of liquid crystal molecules, and the plurality of liquid crystal molecules have the same fixed orientation angle, and an orthogonal projection of long axes of the liquid crystal molecules on the first substrate is perpendicular to an absorption axis of the first polarizer. As such, the brightness of the display screen will not be affected when looking up from the front, and the privacy-image protection effect for decreasing the brightness of the display screen when looking up from the side is achieved.
