A peep-proof film (100) and a display apparatus (200). In a first mode, an included angle between a long axis of a liquid crystal molecule (21) in a liquid crystal dimming layer (20) and a plane where a polarizer (10) is located is set to be an acute angle, such that an included angle is formed between an effective long axis of the liquid crystal molecule (21) in the liquid crystal dimming layer (20) in a side view direction and the direction of polarized light, and therefore light in the side view direction of the peep-proof film (100) is dark, thereby realizing peep prevention; and sharing can be realized in a non-first mode.
