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.
