Abstract: Provided is a display panel. The display panel includes: a substrate, at least one row of light-emitting elements disposed on the substrate, a plurality of pixel drive circuits, a plurality of connection lines, and a plurality of compensation portions. A length of a first connection line electrically connected to a first pixel drive circuit is less than a length of a second connection line electrically connected to a second pixel drive circuit. A capacitance of the first connection line is compensated by electrically connecting the compensation portion to the first connection line, and thus a difference between the capacitance of the first connection line and a capacitance of the second connection line is reduced.

Abstract: The present disclosure discloses a display panel and a display device. The display panel includes a base substrate including a first display region and a second display region. Since pixel circuits for driving light-emitting elements in the second display region are only disposed in the first display region but not disposed in the second display region, the light transmittance of the second display region is ensured to be good. Correspondingly, the display panel in the present disclosure has a good display effect.
