Abstract
Disclosed are a display panel and a display device. The display panel includes an organic light-emitting display panel, a fingerprint identification module and an angle defining film; the fingerprint identification module includes at least one fingerprint identification unit, and performs fingerprint identification according to lights reflected to the fingerprint identification unit via a touch body; the angle defining film is located between the organic light-emitting display panel and the fingerprint identification module. A transmissivity of the light by the angle defining film is Awhen the incident angle of said light with respect to the angle defining film is smaller than a transmission angle of the angle defining film, and a transmissivity of the light by the angle defining film is Awhen the incident angle of said light with respect to the angle defining film is larger than the transmission angle of the angle defining film, wherein A>A>0.
