    Abstract: A display device includes a substrate including first and second substrates, and first and second barrier layers, and a pad unit disposed in a non-display area of the substrate and including pads connected to a driving board under the first substrate. Each of the pads includes an inorganic layer and a pad electrode in a pad contact hole defined through the second substrate and the second barrier layer, a rear pad line on the first barrier layer and connected to the pad electrode through a middle hole defined through the inorganic layer, and a rear pad electrode extending from the rear pad line and connected to the driving board through a rear contact hole defined through the first substrate. A pad defining layer including a laser absorption layer and the first barrier layer and a protrusion pattern covering the pad defining layer are disposed between neighboring rear pad electrodes.
