摘要： A unit display screen, a splice display screen and a display device are provided. The unit display screen comprises a display panel and a frame surrounding the display panel, wherein the frame comprises a first frame which includes a first part (21a) and a second part (21b) sequentially in a direction away from the display panel, the second part (21b) protruding towards an outer side of the display panel with respect to the first part (21a) and having a chamber for accommodating a circuit board (41) and a wire (51). The unit display screen can solve the problem of widening the splicing seam in prior art caused by shielding the circuit board and the wire.
