Abstract: A spliced screen and a display device are provided. A light-emitting unit is arranged and covers the area between display areas of a two unit screens. When the display area of the unit screens normally functions, a plurality of light-emitting units on a light bar can be transmitted and displayed synchronously, cover an area which cannot be shown between the display areas of the two unit screens, and further, weaken or eliminate a slit visually. In this way, the display screen of each of the unit screens is coherently connected to the display screen, and the visual screen-to-body ratio increases as well.
