Disclosed are a display panel and a display device. The display panel includes multiple sub-pixels and multiple data signal lines. The multiple sub-pixels constitute multiple sub-pixel columns; each sub-pixel column includes multiple sub-pixels arranged in sequence; every three adjacent sub-pixels or every four adjacent sub-pixels form a pixel unit; and colors of sub-pixels in each pixel unit include red, green and blue; at least part of sub-pixels belonging to a same sub-pixel column share one data signal line, and sub-pixels sharing one data signal line receive data signals transmitted by the one data signal line in a time-division manner; where a data signal line electrically connected to red sub-pixels is different from a data signal line electrically connected to blue sub-pixels, and a data signal line electrically connected to green sub-pixels is different from the data signal line electrically connected to the blue sub-pixels.
