摘要： An optical element (8) is provided on a substrate, for example a display screen (3) of a display device (1), which optical element comprises a light-transmitting layer whose transmission in the visible region varies in response to a change in ambient light. The optical element (8) is characterized in that it further comprises a colored coating which selectively absorbs light in the visible region. The colored coating has such an absorption characteristic that the color coordinates (x;y) of the combination of the light-transmitting layer and the colored coating vary in such a way, as a result of a variation in ambient light, that a line, which interconnects the color coordinates, is partly situated in an elliptical area with achromatic point (0.333;0.333) in the color triangle, which ellipse comprises a major axis and a minor axis, which major axis terminates in (0.30;0.28) and (0.36;0.38) and the eccentricity of which ranges between 2 and 3. Preferably, the line is situated predominantly in the elliptical area. The invention is important, in particular, for optical elements which serve to reduce the transmission of light, and which comprise an electrochromic element or a photochromic element.

摘要： The optical element (29) comprises a substrate (28) provided with a light-transmitting layer (20) whose transmission in the visible range varies in response to a variation in light. The optical element (29) is characterized in that an anti-reflective layer (21) is provided between the substrate (28) and the light-transmitting layer (20), the refractive index of said anti-reflective layer preferably ranging from 1.5 to 2.2. The light-transmitting layer (20) may further be provided, on a side of the light-transmitting layer (20) facing away from the substrate, with a further anti-reflective layer (22) having a refractive index which preferably ranges between 1.3 and 1.6. The light-transmitting layer may comprise an electrochromic element (20) as well as a photochromic element. The optical element (29) is preferably provided on the outside of the display window (28) of a display device.
