Abstract: An organic light-emitting display apparatus includes a substrate divided into a display area and a peripheral area that is around the display area. Pixels are formed over the display area. For each pixel, a thin film transistor is provided. An insulation film covers the thin film transistor. Each pixel includes a pixel electrode disposed on the insulation film and electrically connected to the thin film transistor, a pixel defining layer covering an edge area of the pixel electrode, an opposite electrode facing the pixel electrode, and an organic light-emitting layer disposed between the pixel electrode and the opposite electrode. The pixel defining layer includes an opening to expose a center area of the pixel electrode, a first inclination portion, and a second inclination portion. An end of the pixel electrode is disposed between the insulation film and the second inclination portion.

Abstract: A conductive material layer for forming a conductive pattern is formed on a substrate. A photosensitive organic material layer is formed on the conductive material layer. The photosensitive organic material layer is irradiated through a halftone mask. The halftone mask includes a first mask region having a boundary corresponding to an edge of the conductive pattern, a second mask region, and a third mask region disposed between the first mask region and the second mask region. A first pattern including a first region corresponding to the first mask region and a second region corresponding to the third mask region is formed by removing the photosensitive organic material layer. The conductive material layer is etched using the first pattern as a hard mask to form the conductive pattern having exposed lateral surfaces. A second pattern is formed that covers the lateral surfaces of the conductive pattern by reflowing the first pattern.
