An organic light-emitting diode (OLED) display is disclosed. In one aspect, the OLED display includes a substrate including a display area in which an OLED is formed and a non-display area surrounding the display area. The OLED display also includes a pixel defining layer formed over the substrate and having an opening defining an emission area of the OLED, a first passivation layer covering a portion of the pixel defining layer formed in the non-display area and a second passivation layer formed in the non-display area, wherein a portion of the second passivation layer does not overlap the first passivation layer in the depth dimension of the OLED display. The OLED display further includes an encapsulation substrate formed to be opposite to the substrate and a filler filling a space between the substrate and the encapsulation substrate and contacting the first and second passivation layers.
