Anti-peep display screen, vehicle-mounted display device and vehicle

A vehicle-mounted display device, comprising an anti-peep display screen, wherein the anti-peep display screen, comprises:

• a passive liquid crystal display module and a color liquid crystal display module stacked along a first direction;
• wherein, the passive liquid crystal display module comprises a first electrode layer, a liquid crystal layer and a second electrode layer, the first electrode layer comprises a plurality of first sub-electrodes, the second electrode layer comprises a plurality of second sub-electrodes, and the plurality of first sub-electrodes are opposite to the plurality of second sub-electrodes and are configured to receive different voltages, so as to control a light transmission state of the passive liquid crystal display module where the plurality of first sub-electrodes are located;
• wherein the passive liquid crystal display module is a twisted nematic display module;
• and
• wherein a pretilt angle of liquid crystal molecules in the twisted nematic display module is 1°−7°, a twist angle thereof is 80°-100°, and a retardation is 500 nm-1200 nm;
• wherein the plurality of first sub-electrodes are arranged in an array, and a spacing between two adjacent first sub-electrodes of the plurality of first sub-electrodes is 3 μm-10 μm;
• wherein each of the plurality of second sub-electrodes has the same size as each of the plurality of first sub-electrodes, and the plurality of second sub-electrodes are arranged corresponding to the plurality of first sub-electrodes, respectively.
