The invention discloses a display panel and a display device. The display panel comprises an array layer, a luminescent device layer and a light-sensitive device, wherein the array layer is located atone side, away from a display face of the display panel, of the luminescent device layer; the luminescent device layer comprises a plurality of organic light-emitting devices, each organic light-emitting device comprises a positive pole, a luminescent layer and a negative pole, and a film where the negative pole is located is a cathode layer; the light-sensitive device comprises a plurality of induction units, the induction units are located at one side, away from the display face of the display panel, of the cathode layer; a display area of the display panel comprises a luminous zone and non-luminous zone, the cathode layer is provided with a plurality of opening holes, the opening holes are located in the non-luminous zone, and the orthographic projections of the induction units are atleast partly located in the opening holes. The display panel and the display device have the advantages that the light penetration rate of fingerprint identification detecting is improved, thereby increasing the amount of light received by the induction units, and improving the precision of the fingerprint identification detecting.
