Abstract: A display panel and a display device are provided. The display panel includes a fingerprint identification module. The fingerprint identification module includes a light sensor and a light-shielding layer disposed on a light incident side of the light sensor. The light-shielding layer is provided with a light-transmitting hole. A light filter structure is disposed in the light-transmitting hole. The display panel and the display device can filter out red light and near-infrared light entering the fingerprint identification module, so that the display panel can successfully perform fingerprint identifications even in a strong light environment.
