The invention relates to the technical field of display, and discloses a peep-proof display screen which comprises a black and white liquid crystal display module and a color liquid crystal display module which are stacked in the first direction, the black and white liquid crystal display module comprises a first electrode layer, a liquid crystal layer and a second electrode layer, the first electrode layer comprises first sub-electrodes, and the second electrode layer comprises second sub-electrodes. The first sub-electrodes and the second sub-electrodes are opposite and can be used for inputting different voltages so as to control the light transmitting state of the black and white liquid crystal display module. According to the peep-proof display screen, by additionally arranging the black and white liquid crystal display module, the technical problems that an existing peep-proof display screen is poor in display effect and single in peep-proof function are solved. The invention further provides a vehicle-mounted display device and a vehicle.
