Title: PEEP-PROOF DEVICE AND MANUFACTURING METHOD THEREFOR, AND DISPLAY DEVICE
Abstract:
Disclosed is a peep-proof device, comprising a transparent body (10) and a plurality of shielding pieces (20), wherein a plurality of accommodation grooves (12) used for accommodating the shielding pieces (20) are formed on the transparent body (10); the plurality of shielding pieces (20) are provided at intervals; portions of the transparent body (10) between two adjacent shielding pieces (20) are light-transmitting units (30); and the light-transmitting units (30) each comprise a light incident surface and a light-emitting surface. Side faces of the shielding pieces (20) adjacent to the accommodation grooves (12) form reflection surfaces for reflecting at least some of the light rays, wherein same radiate from the light incident surfaces of the light-transmitting units (30) to the shielding pieces (20), towards the light-emitting surfaces of the light-transmitting units (30). The light reflection surfaces of the shielding pieces (20) are configured in such a manner that an included angle (β) between a reflection direction of a light ray reflected by the reflection surface and the light-emitting surface of the corresponding light-transmitting unit (30) is larger than an included angle (η) between a light incidence direction of a light ray radiating to the reflection surface and the light incident surface of the corresponding light-transmitting unit.
