ABSTRACT:
A rear plate of a liquid-cell display device has louvers embedded therein that allow light to pass from the rear of the display device toward the front only at angles that will cause most or all of the light to be internally reflected at the front plate unless the light has been scattered by the light-scattering fluid of the device.
