Zusammenfassung:	Anti-peep display assembly and display device are provided. The anti-peep display assembly includes a backlight module, a first birefringence control type liquid crystal cell, a second birefringence control type liquid crystal cell, and a display liquid crystal cell. Along a thickness direction of the anti-peep display assembly, the first birefringence control type liquid crystal cell and the second birefringence control type liquid crystal cell are between the backlight module and the display liquid crystal cell, and the first birefringence control type liquid crystal cell is between the second birefringence control type liquid crystal cell and the backlight module. A first polarizer is arranged on a side of the display liquid crystal cell away from the second birefringence control type liquid crystal cell, and a second polarizer is arranged between the display liquid crystal cell and the second birefringence control type liquid crystal cell.
