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 orientation direction of a retardation layer (31, 32) is aligned with respect to the polarization direction of the polarizing mirror to give optimal optical performance.
