摘要： 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.

摘要： 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.

摘要： A display apparatus includes a display panel (DP) and a sensor unit on the DP. The sensor unit includes: a first conductive layer (CL) including a first bridge (FB); a second CL disposed on the first CL, the second CL including first sensor portions (FSPs) spaced apart from each other and arranged in a first direction; a first insulating layer (IL) disposed between the first CL and the second CL, the first IL including through-holes (THs) extending between the FB and the FSPs overlapping the FB; and contact electrodes (CEs) filling spaces defined by a bridge top surface of the FB exposed by the THs, insulating sidewalls of the first IL defining the THs, and sensor bottom surfaces of the FSPs facing the FB. A cross-section, which is perpendicular to a top surface of the DP, of each of the CEs has a polygonal shape of five or more sides.
