Abstract
A liquid crystal antidazzle mirror for supplying a power to liquid crystal drive control circuit when a key plate is inserted into a key cylinder which comprises a key position detecting switch for detecting that the key plate is inserted into the key cylinder, and an initializing circuit for initializing the liquid crystal drive control circuit to either special mode of predetermined antidazzle or dazzle state upon receiving a detection signal of the key position detecting switch. Thus, the antidazzle mirror can automatically initialize the antidazzle mirror to either special mode of a predetermined antidazzle and dazzle states when power is supplied from a battery.
