Abstract
A display assembly is disclosed including an electro-optical cell ( ), for example a liquid crystal cell, and a photovoltaic cell ( ) acting as a back reflector. In order to improve the aesthetic appearance of the display, the photovoltaic cell ( ) reflects predetermined wavelengths and thus exhibits a desired color in the transparent zones ( ) of the electro-optical cell. In particular, the reflected light can be colored by reflection onto a multi-layered reflective filter including a transparent electrode ( ) of the photovoltaic cell. This cell may form part of the dial of a watch.
