Liquid crystal dazzle-free reflection mirror
First Claim
1. A liquid crystal type dazzle-free reflection mirror comprising:
- a scattering liquid crystal cell switching, depending on an electric field applied thereto, the orientation of liquid crystal molecular axis thereof between a random orientation and a regular orientation;
a coloring filter cell provided at a front side of said scattering liquid crystal cell to which light is incident and switching, depending on an electric field applied thereto, between two light transmitting states in one and the other of which the light transmitted therethrough is colored and decolored;
a reflection mirror layer reflecting the light transmitted from said coloring filter cell through said scattering liquid crystal cell; and
control means responsive to a light incident thereto for controlling the electric fields applied to said scattering liquid crystal cell and said coloring filter cell so that said scattering liquid crystal cell provides the random orientation and the coloring filter cell colors the light when the incident light is intensive.

Abstract
A liquid crystal type dazzle-free reflection mirror has a scattering type liquid crystal cell such as DSM liquid crystal switching the orientation of the liquid crystal molecular axis thereof between a random orientation and a regular orientation depending on an electric field applied thereto. At least one coloring filter cell such as guest-host liquid crystal provided at a front side of the scattering type liquid crystal cell to which light is incident and switching, depending on an electric field applied thereto, between two light transmitting states in which white light is transmitted and specific color light is transmitted more, respectively. A reflection mirror layer reflecting the light transmitted through the scattering type liquid crystal cell and the coloring filter cell is provided behind the scattering type liquid crystal cell so that a reflection image may be provided on the mirror surface.
