Abstract
A rear-view mirror arrangement for a motor vehicle, having a mirror assembly held on a carrier plate. The mirror assembly includes a liquid-crystal cell to view following traffic, and which has a variable reflectance controllable via a control device. The mirror assembly has a transparent plate arranged on a front side thereof and a rear-side reflective coating adjacent to and pointing toward the carrier plate. The rear-view mirror arrangement is automatically dimmable and heatable, and includes an optical liquid-crystal cell to produce a permanently clear optical image for the vehicle occupant as a user. In order to provide a heatable effect, an areal heating element is arranged on the carrier plate to generate thermal radiation, and a housing gap is disposed between the carrier plate and the mirror assembly such that the thermal radiation is to transmitted to a radiation-absorbing coating arranged on a reflective coating of the mirror assembly.
