Abstract:
The present application discloses a display panel and a display device. The display panel comprises: a substrate; a light-emitting layer, located on one side of the substrate and comprising a plurality of light-emitting units arranged at intervals, pixel definition blocks being provided between adjacent light-emitting units; and a low-refractive-index film layer and a high-refractive-index film layer, provided on the side of the light-emitting layer away from the substrate. The low-refractive-index film layer is provided with a plurality of microstructures, and the high-refractive-index film layer covers at least part of the surface of the microstructures. The orthographic projection of the microstructures on the light-emitting layer covers the light-emitting units at corresponding positions, and in the thickness direction of the display panel, a plurality of fully reflecting interfaces are formed between the microstructures and the high-refractive-index film layer. In this way, the present application can reduce large-view-angle light exit from the display panel, thereby realizing privacy protection.
