    Abstract: The invention relates to a light-protected electrochromic device containing a pair of glass or plastic sheets or plastic films. One side of at least one of said sheets or films, preferably both sheets or films, is provided with an electroconductive coating. At least one of said sheets or films and its electroconductive coating are transparent and the other can be metallized. The electroconductive coating of at least one of the two sheets or films can be divided up into separate, individually contacted surface segments. The sheets or films are joined by a sealing ring on the sides of their electroconductive coatings and the volume created by the sheets or films and the sealing ring is filled with an electrochromic medium. The invention is characterized in that the electrochromic device contains a yellow filter for which the wavelength at which absorbance in the long-wave flank reaches half of the very long-wave maximum absorbance value is between 370 and 500 nm, preferably between 380 and 470 nm. The invention is characterized by a considerably improved resistance to light in its activated state.
