摘要： 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.

摘要： A display substrate includes a base, and first data lines, second data lines, a plurality of sub-pixels and voltage signal lines disposed on the base. The first data lines and the second data lines are alternately arranged in a first direction. Each column of sub-pixels includes first sub-pixels and second sub-pixels that are alternately arranged in a second direction. In the column of sub-pixels, the first sub-pixels are electrically connected to a first data line located on a side of the column of sub-pixels and adjacent thereto, and the second sub-pixels are electrically connected to a second data line located on another side of the column of sub-pixels and adjacent thereto. An orthogonal projection of each voltage signal line on the base is located between orthogonal projections of a first data line and a second data line between two adjacent columns of sub-pixels on the base.
