The invention discloses a display panel and a display device. A lens imaging unit and a photosensitive element are integrated in a pixel unit of the display panel, thereby replacing the use of a camera, and reducing the cost of the display panel; through the imaging of the lens imaging unit, not only is the cross-talking of the light reduced, but also is the imaging quality of an edge visual fieldof the display panel greatly promoted; the display panel comprises a first substrate and a second substrate arranged in opposite, and multiple pixel units arranged in an array; the pixel unit comprises an imaging acquisition region; the display panel further comprises a photosensitive element arranged at one side of the second substrate facing to the first substrate and corresponding to the imaging acquisition region, and a lens imaging unit arranged at one side of the first substrate far away from the second substrate and in one-to-one correspondence to the photosensitive element.
