NOVELTY - The mirror has a blind spot indicator light display with LED to emit visible light upon detection by a blind spot detector. The display is arranged at rear side of mirror reflector arranged on transparent glass substrate (2,3) and configured so that emitted light is passed through transparent glass substrate. The display is operable to exhibit a display luminance of at least about 60 foot lamberts. A mirror reflector is comprised of elemental semiconductor thin film layer and metal thin film layer made of chromium, titanium and metal alloy, and combined with a metal oxide thin film layer.    USE - Blind spot indicator mirror for vehicle e.g. truck and aircraft. Can also be used as electrochromic rearview mirror, interior mirror, exterior mirror, architectural mirror and specialty mirror used in aeronautical, periscopic or dental and medical applications, and for electrochromic glazing such as architectural glazing used in home, office or other edifice, aeronautical glazing used in aircraft, vehicular glazing, windshield, side window and backlight, sun roof, sun visor or shade band, electrochromic optically attenuating contrast filter such as contrast enhancement filter, cathode ray tube monitor, electrochromic solar panel, electrochromic information display, electrochromic lens and eye glass.    ADVANTAGE - The non-spectral selectivity of light when dimmed to a colored state can be provided. The manufacturing cost associated with a separate transparent conductive electrode coating can be reduced and the resistance of the reflective material to physical, chemical and/or electrochemical degradation can be enhanced. The image separation which can lead to the recognized problem of double imaging can be reduced. The lifetime of the electrochromic device can be increased and the driver's field of view can be increased. The driver can be enabled to see safely and to avoid blind-spots in the rearward field of view. The manufacturing requirements of the mirror can be minimized. The safety during driving of vehicle can be ensured by retaining any glass shards which may result due to mirror breakage.
