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. The second planarization layer may planarize the polarizer at the edges of the active area of the display where the polarizer would otherwise have a steep taper. Planarizing the polarizer in this way mitigates undesirable secondary reflections off of the polarizer. The first and second planarization layers may be formed from organic material.
