The present disclosure provides a display panel and a display device, the display panel includes a first substrate, the first substrate defines a photoresist layer; a second substrate, the second substrate defines an identification region, a surface of the first substrate having the photoresist layer faces a surface of the second substrate having the identification region; and a frame glue, the frame glue is defined between the first substrate and the second substrate, and the frame glue encloses a space between the first substrate and the second substrate to form a filling area, and the identification region is defined at the outside of the frame glue; the photoresist layer defines an anti-overflow groove located at an area between the identification region and the frame glue.
