Abstract
An organic light-emitting diode (OLED) display according to an exemplary embodiment of the present invention includes a substrate, a thin film transistor formed on the substrate, a pixel electrode formed on the thin film transistor and electrically connected to the thin film transistor, a pixel definition layer formed on the pixel electrode so as to define a pixel region, an emission layer formed on the pixel electrode and contacting the pixel electrode in the pixel region, and an interlayer formed on the pixel definition layer and contacting part of the emission layer. One side of the interlayer has an uneven shape so that a surface area of the interlayer is increased.
