Abstract
The invention relates to a transflective LCD incorporating a partial mirror (224) as the transflector. In the transmissive display mode, light from a backlight system (240) passes apertures (226) in the transflector (224). According to the invention, recycling of light to the backlight system (240) is improved by substantially only polarizing light that passes an aperture. This is achieved by means of a patterned polarizer (222) extending over the apertures in the partial mirror.
