Abstract: A display includes a wiring pad and a dummy pad on a first substrate. A first planarization layer is disposed on the wiring pad and the dummy pad. A first pad electrode layer is connected to the wiring pad and a second pad electrode layer is connected to the dummy pad. The first and second pad electrode layers are disposed on the first planarization layer. A first insulating layer covers the first and second pad electrode layers. A first pad electrode upper layer is disposed on the first pad electrode layer. A second pad electrode upper layer is disposed on the second pad electrode layer. The wiring pad, the first pad electrode layer, and the first pad electrode upper layer are electrically connected. The dummy pad, the second pad electrode layer, and the second pad electrode upper layer are electrically connected.
