摘要： The present application proposes a display panel and a display device, the display panel includes a liquid crystal display module, a reflective film and a fingerprint identification module. The liquid crystal display module is on a first side of the reflective film, and the fingerprint identification module is on a second side of the reflective film opposite to the first side. The fingerprint identification module includes an invisible light emitting unit and an invisible light sensor. The invisible light emitting unit is configured to emit invisible light in a direction towards the reflective film, and the invisible light sensor is configured to receive reflected invisible light. The reflective film is configured to transmit the invisible light and reflect visible light reaching the reflective film through the liquid crystal display module.
