This invention discloses an electronic paper display panel and a display device. The display panel includes: multiple data lines and multiple scan lines; and sub-pixels enclosed by the multiple data lines. The data lines are serpentine, with two data lines between adjacent columns of sub-pixels. Each pair of adjacent rows of sub-pixels is connected to a scan line, and within the same column, each pair of sub-pixels is not completely enclosed by two data lines. The two rows of sub-pixels are respectively connected to left and right data lines. The display panel provided by this invention, by setting the data lines in a serpentine pattern, with at least a portion of adjacent columns of sub-pixels having two data lines between them; each pair of adjacent rows of sub-pixels is connected to a scan line, and within the same column, each pair of sub-pixels is not completely enclosed by two data lines. The two rows of sub-pixels are respectively connected to left and right data lines. This reduces the intersection of signal lines on the bottom bezel of the electronic paper display panel, saves costs, facilitates the realization of a narrow bezel in the electronic paper display panel, and improves the display effect.
