The embodiment of the invention provides an optical composite film, a preparation method and a display panel. The optical composite film comprises a polarization layer, a first refraction layer and a second refraction layer, the first refraction layer comprises a plurality of protrusions arranged at intervals and a plurality of openings located between the protrusions, the openings are filled with the second refraction layer, and the refractive index of the first refraction layer is smaller than that of the second refraction layer. The outer contour surfaces of the sides, close to the polarization layer, of the protrusions at different positions of the opening area are arranged to be concave curved surfaces, and the first refraction layer and the second refraction layer are obtained through illumination, namely developing treatment, so that the preparation precision of the film layer is effectively improved, and the action effect on light is improved. 本发明实施例提供一种光学复合膜及制备方法、显示面板。该光学复合膜包括偏振层、第一折射层以及第二折射层，其中，第一折射
