Abstract: A thin film transistor is disposed on a substrate. A via insulating layer having a via hole covers the thin film transistor. A pixel electrode is disposed on the via insulating layer and electrically connected to the thin film transistor through the via hole. A first protection layer surrounds the pixel electrode. A pixel-defining layer covers an edge region of the pixel electrode and at least a portion of the first protection layer. The pixel-defining layer includes an opening through which an upper surface of the pixel electrode is exposed. An opposite electrode faces the pixel electrode. An intermediate layer is disposed between the pixel electrode and the opposite electrode.

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.
