Disclosed are a display panel and a display device. The display panel includes a base substrate; a pixel unit on the base substrate and including a pixel circuit and a light-emitting element, the pixel circuit being configured to drive the light-emitting element, the pixel circuit being closer to the base substrate than the light-emitting element and including a driving transistor; a data line configured to provide data signal to the pixel circuit; a connection element through which the light-emitting element is connected with the pixel circuit, the connection element including a shielding portion; and a connection line connected with a gate electrode of the driving transistor. The data line includes two adjacent data lines with the shielding portion located therebetween, and an orthographic projection of the connection line on the base substrate at least partially overlaps with an orthographic projection of the shielding portion on the base substrate.
