Anti-peeping display device and Anti-peeping display device for vehicles

Abstract

A privacy display device includes a first region and a second region, and comprises a first substrate, a second substrate, a plurality of display units, a plurality of first light-shielding structures, and a plurality of second light-shielding structures. The plurality of display units and the plurality of first light-shielding structures are located between the first substrate and the second substrate. The plurality of second light-shielding structures are located on one side of the second substrate relative to the first substrate, and each overlaps its corresponding first light-shielding structure. The center-line distance between a second light-shielding structure in the first region and its corresponding first light-shielding structure is different from the center-line distance between a second light-shielding structure in the second region and its corresponding first light-shielding structure; or, the distance between a second light-shielding structure in the first region and its corresponding first light-shielding structure is different from the distance between a second light-shielding structure in the second region and its corresponding first light-shielding structure. Furthermore, a privacy display device for vehicles is also provided.
