Display panel and display device

The invention provides a display panel and a display device. The display panel comprises a substrate, a light-emitting layer is arranged on one side of the substrate, the light-emitting layer comprises light-emitting units distributed in an array mode, and a light-transmitting hole is formed between at least one set of two adjacent light-emitting units; a first refraction structure is arranged onone side, away from the substrate, of the light-emitting layer; and a second refraction structure is arranged on the side, away from the light-emitting layer, of the substrate. Multiple beams of incident light pass through the first refraction structure and then are refracted to form multiple beams of first refracted light; the plurality of beams of first refracted light are incident to one side surface, far away from the substrate, of the second refraction structure through the light-transmitting holes; the multiple beams of first refracted light are refracted to form multiple beams of secondrefracted light after pas
