The present application discloses a display panel and a display device. The display panel includes a fingerprint recognition area. The display panel includes a cover plate and an optically transparent layer. The optically transparent layer at least covers a portion of the cover plate located in the fingerprint recognition area. A refractive index of the optically transparent layer is greater than a refractive index of air and less than a refractive index of a finger. A thickness of the optically transparent layer is an even multiple of a half-wavelength of a fingerprint recognition light ray. Half-wave loss and interference of light are used to improve fingerprint recognition performance.

Display panel and display device

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.
