Abstract: An electronic device may have a display such as an organic light-emitting diode display. The organic light-emitting diode (OLED) display may have an array of organic light-emitting diode pixels that each have OLED layers interposed between a cathode and an anode. A first passivation layer, a first planarization layer, and a second passivation layer may be formed over the cathode. The first and second passivation layers may be formed from inorganic material. A second planarization layer may be formed over the second passivation layer between the second passivation layer and a polarizer.
