An anti-peeping assembly and a manufacturing method thereof, a method for controlling an anti-peeping assembly and a display device are described. The anti-peeping assembly includes a first substrate and a second substrate arranged facing each other, and a liquid crystal layer located between said first substrate and said second substrate; wherein, a first electrode is disposed on said first substrate at a side near the liquid crystal layer, and a plurality of second electrodes arranged as an array are disposed on said second substrate at a side near the liquid crystal layer; and wherein, in response to applying a same voltage to said first electrode and any second electrode, liquid crystals between said first electrode and said any second electrode scatter light, and in response to applying different voltages to said first electrode and said any second electrode, liquid crystals between them transmit light.
