Abstract

Provided are a display panel and a display device. In a repeating unit of the display panel, two first sub-pixels and two second sub-pixels form an arrangement with two rows and two columns, a row direction and a column direction of the arrangement are parallel to a row direction and a column direction of a matrix respectively, and two sub-pixels in a same row or a same column emit light of different colors. Outer edges of the two first sub-pixels and the two second sub-pixels are located on a same first virtual rectangle, and geometric centers of the two first sub-pixels and the two second sub-pixels form a first virtual parallelogram. Geometric centers of four third sub-pixels form a second virtual rectangle, and one side of the second virtual rectangle is parallel to the row direction or the column direction of the matrix.
