Abstract: Described are examples of display devices including a display panel comprised of a transparent layer, a color filter layer adjacent to the transparent layer, wherein the color filter layer comprises a matrix of colored light filters, and a black matrix layer comprising a base portion disposed on the transparent layer between two of the different colored light filters and an extension portion that extends into the color filter layer between the two colored light filters to block a light path that may otherwise traverse both of the two colored light filters. The base portion and the extension portion differ in a height dimension that is substantially perpendicular to the transparent layer.
