Each of the light boards includes a top surface including a first surface and a second surface connected to the first surface and disposed on a side of the first surface close to the splicing seam. A plurality of columns of first light-emitting elements are disposed on the first surface. A plurality of second light-emitting elements are disposed on the second surface. At least two columns of the plurality of second light-emitting elements are disposed on the second surface along a direction close to the splicing seam. The first light-emitting elements per column or the second light-emitting elements per column are arranged along an extending direction of the splicing seam. Central light-emitting directions of the second light-emitting elements incline in a direction towards the splicing seam.
