Abstract

PURPOSE: To protect the driver's eyes, by providing transparent polarizing plate and liquid crystal cell in the mirror of an automobile or the like, and controlling the transparency of the liquid crystal cell according to the intensity of light when light larger than specified quantity continuously enters a photo sensor attached to part of the mirror.
CONSTITUTION: A liquid crystal cell 15 has a mirror body 16 fitted to its back side, and has the surface is covered with a transparent plate 13 and a polarizing filter 14. A fritted substrate 17 for integrated circuit is provided behind the liquid crystal cell 15. When light enters a photo sensor 5 provided in part of the frame part 2 of a mirror part 1, a voltage corresponding to the intensity of the light is output, and is amplified in an amplifier 20 to be applied to a delay circuit 21, thereby providing a delay corresponding to the capacity of a capacitor C1. When the light continues to enter longer than this time width of delay, the delay circuit 21 sends its output to a monostable multivibrator, and the output from an oscillator 22 for driving the liquid crystal cell is sent to the liquid crystal cell 15 through a driver 24. Therefore, the liquid crystal is made turbid depending on the intensity of the light to weaken the reflected light from the mirror, so that the driver's eyes may be protected.
