The optical structure includes a reflective polarizer and an optical film. The optical film includes a matrix and a plurality of first particles dispersed in the matrix. Each of the matrix and the plurality of first particles includes a silicone polyoxamide and an acrylate polymer. For substantially vertical incident light and for at least a first wavelength within a first wavelength range, the reflective polarizer reflects about 60% of a first polarization state and transmits about 40% of an orthogonal second polarization state. Each of the reflective polarizer and the optical film transmits about 60% of the incident light of each of the first polarization state and the second polarization state for at least a second wavelength within a second wavelength range. The optical film has an optical haze and a depolarization ratio for at least the first wavelength. The ratio of the depolarization ratio to the optical haze is less than 0.1. 光学构造体包括反射偏振器和光学膜。该光学膜包括基质和分散于该基质中的多个第一颗粒。该基质和该多个第一颗粒中的每一者包含有机硅聚乙二酰胺和丙烯酸酯聚合物。
