1. A polarizing mirror (1) for viewing purposes having a first plane (2) reflecting light of a first kind of polarization (20′
- ) to a viewing side, the mirror passing light of a second kind of polarization (20″
) and being provided with a display device (5) at its non-viewing side, which display device during use provides light of the second kind of polarization, the polarizing mirror at its viewing side having polarizing means (14) being switchable between two optical states, comprising a liquid crystal layer (7) between two substrates (26,27), at least one of said substrates having orientating means to orient liquid crystal molecules (25) during one of the optical states in at least two orientation directions.

Abstract
A mirror device (1) which can be simultaneously used for display purposes, based on e.g. an LCD display (5) with a polarizing mirror (2) placed in front of it. The polarizing mirror (2) has the characteristics that it does not disturb the transmission of the light from the display to the viewer (3), but does reflect the incident light. A combined viewing angle and reflection problem related to switchable optical components (14) placed in front of the polarizing mirror (2) is overcome.
