Abstract: A display device includes a display substrate comprising a plurality of pixels electrically connected to select lines and data lines; first connection pads disposed on an upper surface of the display substrate and electrically connected to the pixels; and second connection pads disposed on a surface of the display substrate that is different from the upper surface and electrically connected to the pixels, wherein the second connection pads are electrically separated from the first connection pads. This allows the area of a surface of a display substrate that can be occupied by a flexible printed circuit board attached thereto to be increased. As a result, the risk of an open-circuit of the wiring can be reduced, and the operational reliability of the device can be improved.

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.
