Abstract
A display device may include a switching composite layer, a first electrode, a pixel defining layer, an emission layer, a second electrode, an encapsulation layer, a light blocking layer, and a touch sensor. The first electrode is positioned on the switching composite layer. The pixel defining layer covers an edge of the first electrode and has a first opening and a second opening that are spaced from each other. The emission layer is positioned inside the first opening. The second electrode covers the switching composite layer, the pixel defining layer, and the emission layer. The encapsulation layer covers the second electrode. The light blocking layer is positioned on the encapsulation layer. The touch sensor is positioned on the light blocking layer and includes a sensing electrode set. A material portion is positioned inside the second opening of the pixel defining layer and overlaps the sensing electrode set.
