Abstract: A display apparatus includes a substrate, a display unit, a pad portion, and a connection wire. The display unit is on the substrate. The display unit includes a pixel circuit and a display device electrically connected to the pixel circuit. The pad portion is at one side of a peripheral area outside the display unit. The pad portion includes a first conductive layer, a second conductive layer arranged on and electrically connected to the first conductive layer, and a third conductive layer arranged on and electrically connected to the second conductive layer. The connection wire connects the pad portion and the display unit to each other to transmit a signal input to the pad portion to the display device. The connection wire includes a same material as that of the first conductive layer.
