The invention discloses a polyurethane-based organic-inorganic composite material. The composition in parts by weight is as follows: 1-3 parts of polyurethane resin, 1-3 parts of inorganic particles, 1 part of photoinitiator, and 4-6 parts of diluent; After the resin and the photoinitiator are respectively heated to 50-80°C, they are put into the diluent, the inorganic particles are added after fully stirring, and the stirring is continued at room temperature for 1-2 hours to obtain the polyurethane-based organic-inorganic composite material; the above-mentioned polyurethane-based organic-inorganic composite material is obtained; Application of organic-inorganic composite material as an optical functional layer in a display device; the display device at least comprises a substrate substrate, an organic light-emitting layer, and a cover plate, and the optical functional layer is composed of the polyurethane-based organic-inorganic composite material alone, or combined with A low-refractive-index material with a refractive index of less than 1.5 is formed together. |
