description An organic light-emitting diode display may have thin-film transistor circuitry formed on a substrate. A pixel definition layer may be formed on the thin-film transistor circuitry. Openings in the pixel definition layer may be provided with emissive material overlapping respective anodes for organic light-emitting diodes. A cathode layer covers the array of pixels. Patterned metal on the pixel definition layer may assist the cathode layer in distributing a power supply voltage to the organic light-emitting diodes. The patterned metal may be overlapped by patterned black masking material on an encapsulation layer such as a color filter layer. The pixel definition layer may also be formed from metal that is coated with inorganic dielectric. The cathode may be shorted to a metal pixel definition layer through openings in the inorganic coating.
