Abstract
A display device includes a first support plate and a second support plate. A pixel region between the first support plate and the second support plate includes a plurality of pixel wall portions over the first support plate forming a perimeter of the pixel region. A first liquid and a second liquid that is immiscible with the first liquid are disposed in the pixel region. A light-blocking layer is disposed on an inner surface of the second support plate. The light-blocking layer includes a light-blocking portion positioned over a first pixel wall portion of the plurality of pixel wall portions. An electrically conductive layer comprising an electrically conductive portion is disposed on a first surface of the light-blocking portion. A recessed region is aligned with the electrically conductive portion such that a portion of the second liquid disposed within the recessed region contacts the electrically conductive portion.
