A display panel includes: a substrate, a pixel-defining layer disposed on the substrate, and a conductive pattern, a light-emitting layer and a cathode layer which are laminated in a direction perpendicular to and away from the substrate. The pixel-defining layer is configured to define a plurality of pixel regions and a non-pixel region outside the pixel regions on the substrate. The conductive pattern includes: an auxiliary electrode layer disposed in the non-pixel region, wherein a groove is formed in a side wall of the auxiliary electrode layer. The cathode layer includes: a first portion disposed in the pixel region and a second portion disposed in the non-pixel region. The second portion of the cathode layer extends into the groove and is in contact with the groove.
