Abstract
An electronic device may have a display such as a liquid crystal display. A color filter layer may be formed on a display layer such as a transparent substrate layer of the display. The color filter layer may include an array of color filter elements on an inner surface of the transparent substrate layer. The color filter layer may include opaque masking material. In an inactive portion of the display, the opaque masking material may be formed over the color filter elements and interposed between the color filter elements. In the inactive portion of the display, the opaque masking material and the color filter elements may form a ring that serves as a border region surrounding an active portion of the display. In the active portion of the display, the opaque masking layer may be patterned to from an opaque matrix that separates the color filter elements.
