Abstract
A transflective display includes pixels each including a first electrode, a second electrode, a liquid crystal layer associated with the first and second electrodes, and a conductive reflective layer between the liquid crystal layer and the second electrode to reflect ambient light. The conductive reflective layer is insulated from the second electrode and covers less than all of the second electrode to allow backlight to be transmitted through a portion of the pixel not covered by the conductive reflective layer.
