Organic light-emitting diode display

An organic light-emitting diode (OLED) display, including:

• an OLED disposed in a display area;
• a pixel defining layer including a first portion disposed in the display area and a second portion disposed in a non-display area surrounding the display area;
• a first passivation layer covering at least the second portion of the pixel defining layer;
• a second passivation layer disposed in the non-display area, wherein the second passivation layer directly contacts a portion of the first passivation layer and part of the second portion of the pixel defining layer;
• a filler covering the first and second passivation layers;
• and
• a planarization layer disposed below the pixel defining layer and the second passivation layer,
• wherein the second passivation layer does not overlap an emission layer of the OLED display device,
• wherein the planarization layer has an opening exposing an interlayer insulating layer disposed below the planarization layer,
• wherein the second passivation layer directly contacts and covers the exposed interlayer insulating layer and sidewalls of the opening of the planarization layer, and
• wherein the first passivation layer covers a second portion of an upper surface of the second passivation layer in the non-display area, the second passivation layer is disposed under the pixel defining layer and contacts a lower surface of the pixel defining layer in the non-display area, and the first passivation layer overlaps the second passivation layer disposed under the pixel defining layer in the non-display area.
