The invention relates to an electrically dimmable rearview mirror glass (08) having a reflective surface (07) and a liquid crystal assembly (03) having electrically controllable light transmission, an electrical contacting (01) of a corresponding liquid crystal assembly (03) and of a conductor path carrier (02), and a rearview mirror for a vehicle provided with a rearview mirror glass (08) of this type and a corresponding electrical contacting (01). The electrical contacting (01) provides that the liquid crystal assembly (03) comprises a liquid crystal film (30) which is arranged between two electrically conductive layers (31, 32) and which can be electrically controlled in terms of its light transmission in accordance with a variable voltage applied at the two electrically conductive layers (31, 32), wherein an electrically insulating seal (34) between the two electrically conductive layers (31, 32) is arranged in a peripheral edge region (33) of the liquid crystal assembly (03). The conductor path carrier (02) comprises at least one first conductor path and at least one second conductor path, which function to supply the variable voltage. Each of the first and second conductor paths is connected to at least one contact arm (20) at a distance from the conductor path carrier (02). The conductor path carrier (02) is arranged on one side of the liquid crystal assembly (03). The contact arms (20) extend from the conductor path carrier (02) to the liquid crystal assembly (03). On the side of the liquid crystal assembly (03) facing the conductor path carrier (02), at least one first contact region (311) is formed that is electrically connected to a first layer (31) of the two electrically conductive layers (31, 32). Via the first contact region (311), the first layer (31) is electrically contactable for a contact arm (20) connected to a first conductor path of the conductor path carrier (02) for the establishment of an electrical connection required for transmitting the variable voltage. On the side of the liquid crystal assembly (03) facing the conductor path carrier (02), at least one second contact region (321) is formed in the edge region (33), in which the seal (34) and the first electrically conductive layer (31) are at least partially hollow, such that, via the second contact region (321), the second layer (32) is electrically contactable for a contact arm connected to a second conductor path of the conductor path carrier (02).
