Abstract: A display panel includes a plurality of sub-panels tiled in sequence along a first direction. The sub-panels have a first edge and a second edge in the first direction. The sub-panels include a column of first pixels closest to the first edge, a column of second pixels closest to the second edge, and a plurality of columns of third pixels between the column of first pixels and the column of second pixels. A sum of a distance between effective display bodies in the first pixels and the first edge and a distance between effective display bodies in the second pixels and the second edge is smaller than a spacing between effective display bodies in two adjacent columns of the third pixels.
