    Abstract: Provided is an anti-peeping device including: a first substrate; a second substrate opposite to the first substrate; a liquid crystal layer between the first substrate and the second substrate; a plurality of first polarizers on the first substrate and being spaced apart from each other; and a second polarizer on the second substrate. Linearly polarized light emitted from the second polarizer is incident onto the plurality of first polarizers through liquid crystal molecules in at least a portion of the liquid crystal layer. The anti-peeping device is switched between a first state and a second state in response to a deflection state of the liquid crystal molecules, wherein the linearly polarized light passes though the plurality of first polarizers in the first state, and the linearly polarized light is blocked by the plurality of first polarizers in the second state.

    Abstract: The present invention provides an array substrate comprising a transparent substrate and a polarizer attached on the transparent substrate, the polarizer comprises a first protective layer in contact with the transparent substrate, and a relational expression is satisfied between the first protective layer and the transparent substrate, 0≤|C|≤1.0×10−13, wherein C is defined by the equation C = C 100 ⁢ ρ 100 ⁢ d 100 ρ 100 ⁢ d 100 + ρ 200 ⁢ d 200 + C 200 ⁢ ρ 200 ⁢ d 200 ρ 100 ⁢ d 100 + ρ 200 ⁢ d 200 . When designing an array substrate provided by this invention, it is not required to consider the improvement of the material of the polarizer, and it may be ensured that the change of photoelastic birefringence of a finally formed array substrate is zero (or close to zero) in the case of being subjected to stress by only adjusting the thickness of a first protective layer or the material of the first protective layer, such that the phenomenon of light leakage of a finally formed liquid crystal display panel generated due to photoelastic birefringence may be eliminated or reduced. This invention further provides a display panel, a display apparatus, and a method for producing an array substrate.
