Abstract
The invention relates to a switching mirror display having an increased aperture. The display comprises pixel elements ( ) having a switchable layer ( ), which is switched between a reflecting and an absorbing state by changing a hydrogen content of the switchable layer ( ). Applying a DC voltage on electroconductive layers ( ) changes the hydrogen content. These electroconductive layers ( ) sandwich a stack of layers comprising the switchable layer ( ), which stack has been deposited on a transparent substrate ( ). The display is being viewed from a side ( ) of the substrate on which the stack is deposited. The pixel element ( ) is driven by an active matrix element ( ). The switchable layer ( ) extends across the active matrix element ( ) and conceals this element. This increases the aperture of the display.
