Display module and display device including transparent adjusting layer

A display device, comprising:

• a display module, the display module including:
• a substrate;
• a light-emitting unit disposed on a side of the substrate, wherein the light-emitting unit includes an opening region and a non-opening region surrounding the opening region;
• and
• a transparent adjusting layer disposed on a side of the light-emitting unit away from the substrate, wherein:
• the transparent adjusting layer includes a first substrate and a second substrate that are disposed opposite to each other, and a liquid crystal sandwiched between the first substrate and the second substrate,
• the transparent adjusting layer includes a first region and a second region surrounding the first region,
• in a direction perpendicular to a plane of the substrate, the first region at least partially overlaps with the opening region, and the second region at least partially overlaps with the non-opening region, and
• a working process of the display module includes an anti-peeping stage, and in the anti-peeping stage, the first region is transparent, and the second region is non-transparent.
