Electronic device

The invention provides an electronic device. The electronic device comprises a substrate, a first conductive layer, an extension piece and an insulating layer, the substrate includes a peripheral region and an edge. The first conductive layer is disposed in the peripheral region. The extension member overlaps the first conductive layer and extends to the edge of the substrate, the extension member includes a second conductive layer and an opening, and the opening passes through the second conductive layer. An insulating layer is disposed between the first conductive layer and the extension. 本发明提供一种电子装置，其包括基板、第一导电层、延伸件以及绝缘层。基板包括一外围区与一边缘。第一导电层设置在外围区。延伸件和第一导电层重叠，并延伸至基板的边缘，延伸件包括一第二导电层与一开口，其中，开口穿过第二导电层。绝缘层设置在第一导电层和延伸件之间。
