Embodiments of the application provide a display panel and display device. The display panel has a display area and a non-display area and includes a touch-control component, including multiple first electrode blocks distributed in sequence along a first direction and multiple second electrode blocks distributed in sequence along a second direction, the first electrode blocks and second electrode blocks being positioned in the display area; and a dummy component including dummy electrode blocks positioned in the display area and dummy traces positioned in the non-display area, each dummy electrode block being positioned between two adjacent first electrode blocks and a second electrode block adjacent to the two adjacent first electrode blocks, wherein there is a first distance S between two adjacent dummy electrode blocks, and a distance from an end of at least one dummy trace to a dummy electrode block is greater than or equal to S/3.
