Abstract
A rear-view mirror arrangement for a motor vehicle, having a housing to hold a mirror assembly which has a liquid-crystal cell, the reflectance of the mirror assembly being variable. The liquid-crystal cell has a transparent front-side carrier layer, a transparent rear-side carrier layer and, an electrically actuable liquid-crystal layer arranged between the carrier layers and held in a sealed-off fashion by way of a seal frame. A permanently clear optical image is produced for the vehicle occupant as a user, and the mirror arrangement has a low weight and is inexpensive to produce. This is achieved in that the housing is of unipartite form and permits frameless retention of the mirror assembly, and a housing gap between the housing element and the mirror assembly into which is fitted a seal for the sealed retention of the mirror assembly in the housing.

9. A rear-view mirror arrangement for a motor vehicle, comprising:
-
a housing having a housing element which is of unipartite form; a mirror assembly framelessly held in the housing by the housing element, the mirror assembly having a variable and controllable reflectance, and a liquid-crystal cell having; a front-side carrier layer that is composed as a first transparent, electrically conductive layer and a first alignment layer, a rear-side carrier layer that is composed as a second transparent, electrically conductive layer and a second alignment layer, an electrically actuable liquid-crystal layer arranged between the front-side carrier layer and the rear-side carrier layer, the electrically actuable liquid-crystal layer containing a liquid-crystal medium, and a seal frame to hold the liquid-crystal layer in sealed-off fashion, the seal frame being arranged between the front-side carrier layer and the rear-side carrier layer, a housing gap between the housing and the mirror assembly; and a seal fitted into the housing gap for a sealed retention of the mirror assembly in the housing, the seal composed of an adhesive which is an epoxy or acrylate. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A rear-view mirror arrangement for a motor vehicle, comprising:
-
a housing having a housing base and an encircling housing rim with a face surface, the housing base and the housing rim forming a receiving space; a mirror assembly framelessly held in the receiving space, the mirror assembly having a liquid-crystal cell having; a first transparent layer that is composed of an electrically conductive material, a second transparent layer that is composed of an electrically conductive material, a third transparent layer that is composed of an electrically conductive material, an electrically actuable liquid-crystal layer arranged between the second carrier layer and the third carrier layer, the electrically actuable liquid-crystal layer containing a liquid-crystal medium, and a seal frame arranged between the first carrier layer and the second carrier layer to hold the liquid-crystal layer in sealed-off fashion, a housing gap between the housing and the mirror assembly; and a seal fitted into the housing gap for a sealed retention of the mirror assembly in the housing. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26)

27. A rear-view mirror arrangement for a motor vehicle, comprising:
-
a housing having a housing base and an encircling housing rim with a face surface, the housing base and the housing rim forming a receiving space; a mirror assembly framelessly held by the housing, the mirror assembly having a liquid-crystal cell having; a first transparent layer that is composed of an electrically conductive material and which covers the face surface of the housing rim and terminates flush with an outer contour of the housing rim, a second transparent layer that is composed of an electrically conductive material and which is arranged in the receiving space, an electrically actuable liquid-crystal layer arranged in the receiving space between the second carrier layer and the third carrier layer, the electrically actuable liquid-crystal layer containing a liquid-crystal medium, and a seal frame arranged in the receiving space between the first carrier layer and the second carrier layer to hold the liquid-crystal layer in sealed-off fashion, a housing gap between the housing and the mirror assembly; and a seal fitted into the housing gap for a sealed retention of the mirror assembly in the housing.
