Abstract: A display panel including a pixel defining layer including a first portion, in which an opening to expose the first electrode is defined, and a second portion, which is disposed on the first portion and overlaps the first portion. A plurality of thin-films are disposed on the second electrode. An insulation pattern is disposed on the plurality of thin-films, overlaps the pixel defining layer, and overlaps the second portion. A distance between the first portion, which overlaps the insulation pattern, of the sensing electrode and the base insulation layer is greater than that between the second portion, which non-overlaps the insulation pattern, of the sensing electrode and the base insulation layer.
