Abstract
A display panel is provided having a first substrate including an electrode configured to generate an electric field and a second substrate including a black mask. The black mask includes an aperture configured to enable light to be transmitted through the aperture, wherein the aperture is at least substantially rectangular and includes corners that are not substantially chamfered. The display panel also includes liquid crystal disposed between the first and second substrates and configured to facilitate passage of light through the display panel in response to the electric field.
