Abstract: An electronic device includes a display panel including a plurality of pixels. A first detection insulating layer is disposed on the display panel. A first conductive pattern is disposed on the first detection insulating layer. A compensation pattern is disposed on the first detection insulating layer. A second detection insulating layer is disposed on the first detection insulating layer and covers the first detection insulating layer, the compensation pattern and the first conductive pattern. A second conductive pattern is disposed on the second detection insulating layer. The first conductive pattern includes a lower surface in contact with the first detection insulating layer. An upper surface faces the lower surface and contacts the second detection insulating layer. Lateral side surfaces extend between the lower surface and the upper surface. The compensation pattern contacts the lateral side surfaces of the first conductive pattern.
