Abstract: The invention is related to thin film optical filters, and can be used in liquid crystal displays (LCD) in order to increase their brightness, and provide savings in energy consumption. According to the invention, a reflective color filter for visible light substantially transmitting a light of the chosen spectral range entering into it and substantially reflecting a visible light of other spectral ranges, includes an odd total number of alternate nonmetallic and metal layers, and the first and last layers are nonmetallic ones, and each metal layer is placed between nonmetallic layers, each nonmetallic layer possesses a refractive index not less than 2.2 and thickness not less than 40 nanometers, and each metal layer possesses the thickness in a range from 10 to 40 nanometers.
