摘要： A display panel, a manufacturing method thereof and a display device are provided. The display panel includes: a photosensitive sensor; a light shield layer disposed on a sensing side of the photosensitive sensor and including at least one first opening and at least one second opening, the first opening and the photosensitive sensor are overlapped with each other in a direction perpendicular to a surface of the display panel, so that light running through the first opening is irradiated to the photosensitive sensor; and an optical processing film disposed in a region of the light shield layer close to the second opening and on at least a portion of a surface of the light shield layer away from the photosensitive sensor, and a light reflectivity of the optical processing film is less than a light reflectivity of the light shield layer.
