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.
Claims20
An anti-peeping film, comprising:
- at least two polarizers;
- and
- a liquid crystal light-adjusting layer disposed between two adjacent polarizers;
- wherein optical axis directions of the at least two polarizers are parallel to each other, and in a first mode, an angle between long axes of liquid crystal molecules in the liquid crystal light-adjusting layer and planes in which the polarizers are located is an acute angle.
A display device, comprising:
- an anti-peeping film comprising:
- at least two polarizers;
- a liquid crystal light-adjusting layer disposed between two adjacent polarizers;
- wherein optical axis directions of the at least two polarizers are parallel to each other, and in a first mode, an angle between long axes of liquid crystal molecules in the liquid crystal light-adjusting layer and planes in which the polarizers are located is an acute angle;
- and
- a display panel disposed on a side of one of the polarizers of the anti-peeping film far away from the liquid crystal light-adjusting layer.
