Anti-peeping film and display device

A display device, comprising an anti-peeping film, wherein the anti-peeping film comprises a plurality of anti-peeping layers staked on each other, each of the anti-peeping layers comprising:

• multiple light-blocking portions arranged in parallel;
• and
• a plurality of light-transmissive portions, each of the light-transmissive portions connected between adjacent two of said light-blocking portions;
• wherein a ratio of a width of each of the light-blocking portions in an arrangement direction to a width of each of the light-transmissive portions in the arrangement direction ranges from 0.045:1 to 0.088:1;
• wherein a number of the anti-peeping layers comprised in the anti-peeping film is from 800 to 8000 layers;
• wherein along a direction from a light incident surface of the anti-peeping film towards a light exit surface of the anti-peeping film, the anti-peeping film comprises a first anti-peeping portion, a second anti-peeping portion, and a third anti-peeping portion stacked on each other;
• and
• each of the first anti-peeping portion, the second anti-peeping portion, and the third anti-peeping portion comprises multiple ones of the anti-peeping layers, a refractive index of each of the light-transmissive portions in the first anti-peeping portion is lower than a refractive index of each of the light-transmissive portions in the second anti-peeping portion, and a refractive index of each of the light-transmissive portions in the second anti-peeping portion is lower than a refractive index of each of the light-transmissive portions in the third anti-peeping portion.

• each of the first anti-peeping portion, the second anti-peeping portion, and the third anti-peeping portion comprises multiple ones of the anti-peeping layers, a refractive index of each of the light-transmissive portions in the first anti-peeping portion is lower than a refractive index of each of the light-transmissive portions in the second anti-peeping portion, and a refractive index of each of the light-transmissive portions in the second anti-peeping portion is lower than a refractive index of each of the light-transmissive portions in the third anti-peeping portion;
• and
• wherein the first anti-peeping portion, the second anti-peeping portion, and the third anti-peeping portion comprise different numbers of the anti-peeping layers.
