A spliced display includes a plurality of display modules and at least one angle limiting assembly. Each display module includes a box and a display. A direction perpendicularly connected to a display side and a back side of the box is defined as a first direction. The display is detachably disposed on the display side of the box. The angle limiting assembly includes a rotation member, a linkage assembly and a connector. The rotation member is rotatably disposed on the box around a second direction perpendicular to the first direction, and has a guiding portion. The linkage assembly is disposed on the rotation member, and includes a linkage portion. When the rotation member rotates, the linkage portion is guided by the guiding portion to linearly move along the second direction. The connector is connected to the linkage assembly. Each display module abuts against an adjacent display module by the connector.

A display device includes: a display module; a frame positioned at the rear side of the display module; a displacement control unit which is positioned between the display module and the frame and of which a position in a front/rear direction on the frame changes according to a rotational direction thereof; a rotating magnet rotatably coupled to the rear surface of the display module and attached to the displacement control unit, wherein when the rotating magnet rotates, the displacement control unit rotates and moves in the front/rear direction. According to the display device, a height difference between display modules arranged adjacent to each other can be easily adjusted.
