A display device is provided including a display substrate with a base layer including an active area and a peripheral area. A circuit element layer is disposed on the base layer, and a display element layer connects to the circuit element layer and provides light. An encapsulation substrate is disposed on the display substrate. A sealing unit is disposed between the display substrate and encapsulation substrate. An input sensing layer is disposed on the encapsulation substrate and includes a first conductive layer and a second conductive layer spaced apart with a sensing insulation layer therebetween. A static electricity blocking unit is disposed on the encapsulation substrate. The static electricity blocking unit includes a first blocking pattern and a second blocking pattern separated by a separation space. A connection pattern connects the first blocking pattern and the second blocking pattern, and a portion of the sealing unit overlaps the separation space.
