Display panel and display device

A display device, comprising a display panel having a display area, a first non-display area, and a second non-display area, the first non-display area being located between the display area and the second non-display area, the display panel comprising:

• a plurality of sub-pixels located in the display area;
• a first data line, a second data line and a third data line that are arranged along a first direction and each extend along a second direction intersecting with the first direction;
• wherein the first data line is electrically connected to M sub-pixels of the plurality of sub-pixels, the second data line is electrically connected to M sub-pixels of the plurality of sub-pixels, and the third data line is electrically connected to N sub-pixels of the plurality of sub-pixels, where 1≤M<N, and both M and N are integers;
• compensation capacitor groups located in the first non-display area, wherein each of the compensation capacitor groups comprises a first compensation capacitor electrically connected to the first data line, and a second compensation capacitor electrically connected to the second data line;
• and the first compensation capacitor and the second compensation capacitor have a same capacitance;
• and
• a peripheral circuit located in the second non-display area,
• wherein the first non-display area has a length gradually decreasing along a direction parallel to the first direction and along a direction from the display area to the second non-display area, and the length of the first non-display area corresponds to a size of the first non-display area along the second direction.
