Abstract: Please replace the abstract originally filed with the following: A display panel and a display device. Because the pixel distribution density in a second display subarea (A12) is lower than that in a first display subarea (A11), the quantities of sub-pixels (pix) connected to scanning lines are not completely the same; a sub-pixel row having the greatest quantity of sub-pixels (pix) in the display panel is taken as a reference sub-pixel row, the quantity of the sub-pixels (pix) of the reference sub-pixel row is taken as a reference value, a sub-pixel row having the quantity of sub-pixels (pix) smaller than the reference value is taken as a compensation sub-pixel row, and a scanning line connected to the compensation sub-pixel row is taken as a first scanning line; the display panel is provided with load compensation units corresponding to at least part of the first scanning lines, and the load compensation units are located in the second display subarea.
