Peep-proof element

The invention provides a peep-proof element which is provided with a first area and a second area. The first electrode is arranged in the first area on the first substrate, and no first electrode is arranged in the second area. The second electrode is arranged in the first area on the second substrate, and no second electrode is arranged in the second area. The liquid crystal layer is arranged between the first substrate and the second substrate. The control circuit is electrically connected to the first electrode and the second electrode, and is used for controlling the voltage between the first electrode and the second electrode, so that the viewing angle of the first area in the first viewing angle mode is different from the viewing angle in the second viewing angle mode. 本发明提出一种防窥元件，具有第一区与第二区。第一电极设置于第一基板上的第一区内，第二区内并没有第一电极。第二电极设置于第二基板上的第一区内，第二区内并没有第二电极。液晶层设置于第一基板与第二基板之间。控制电路电性连接至第一电极与第二电极，用以控制第一电极与第二电极之间的电压，使得第一区在第一视角模式下的可视角度不同于在第二视角模式下的可视角度。
