Claim:
1. An organic light-emitting display apparatus, comprising: a display substrate; a thin film transistor (TFT) on the display substrate; an organic light-emitting diode (OLED) electrically connected to the TFT and including a first electrode on sub-pixels of the display substrate, an intermediate layer on the first electrode, and a second electrode on the intermediate layer; a pixel-defining layer which includes an opening exposing at least a portion of the first electrode; and a sealing substrate covering the OLED, the intermediate layer including a plurality of stacked layers, and a cross-sectional width of the intermediate layer decreasing in a direction perpendicular to the display substrate, the direction perpendicular to the display substrate being a direction away from the display substrate toward the sealing substrate.
