Liquid crystal type dazzle-free transmissive-reflective mirror
 A liquid crystal type dazzle-free reflection mirror arrangement which changes reflectivity of the incident light by way of changing the transmittivity of the incident light through a liquid crystal provided within a frame body is disclosed. A semitransparent mirror is positioned behind the liquid crystal and a photo sensor is positioned behind the semitransparent mirror. When the photo sensor detects that the intensity of the incident light passing through the semitransparent mirror, an alternating current electric field is applied to the liquid crystal which responsively decreases the transmittivity of the incident light. A heater for heating the liquid crystal is activated when a door of an automobile is opened and the temperature of the liquid crystal is low.
