A display panel and a display device are provided, and a technical field in displays is related. The display panel includes an array substrate, a liquid crystal layer, a color filter layer, a sensor layer, a glass substrate, and a collimator mechanism. The sensor layer includes a plurality of fingerprint recognition units. The collimator mechanism is disposed on a side of the sensor layer away from the color filter layer. The display device includes the display panel. Display function, touch function, and fingerprint recognition function are integrated into one, by manufacturing the fingerprint recognition units on the glass substrate on the display panel. The cost and the module thickness are further optimized. A fingerprint recognition area is realized as a full-screen area, and fingerprints can be recognized at any position on the screen.
