Mirror with dazzle light attenuation zone

A liquid-crystal matrix-type reflection mirror with a localized dazzle light attenuation zone, said mirror having a multilayered structure and comprising:

• a broadband reflective base mirror having maximum reflectivity in the range corresponding to spectral range of halogen lamps of automobile headlights;
• a matrix transparent electrode on said broadband reflective base mirror;
• a photoconductive layer on said matrix transparent electrode, said photoconductive layer and said matrix transparent electrode having a matrix-type structure formed as a pixel array, each pixel of said matrix transparent electrode being a projection of an overlaid pixel of said photoconductive layer;
• a rear polarizer on said photoconductive layer, said rear polarizer having a predetermined axis of polarization;
• a common transparent electrode above said rear polarizer;
• a liquid crystal sandwiched and sealed between said rear polarizer and said common transparent electrode;
• a front polarizer on said common electrode and having an outer surface, and an axis of polarization parallel to said predetermined axis of polarization;
• and
• a control circuit connected between said common transparent electrode and said matrix transparent electrode, said control circuit having means for applying a voltage to said common transparent electrode and said matrix transparent electrode.
