A display device having a touch sensor and a manufacturing method thereof. The display device includes a pixel defining layer, first electrodes, an emissive layer, second electrodes, and an insulating layer. The first electrodes are exposed and arranged through the pixel defining layer. The emissive layer is formed on each first electrode. Each second electrode is connected to the emissive layer, and the second electrodes are arranged to be spaced apart from each other. The insulating pattern is formed on the pixel defining layer exposed between adjacent second electrodes.
