Abstract: A display substrate includes a gate line, a gate insulation layer, a data line, a switching element, a protection insulation layer, a gate pad portion and a data pad portion. The gate insulation layer is disposed on the gate line. The switching element is connected to the gate line and the data line. The protection insulation layer is disposed on the switching element. The gate pad portion includes a first gate pad electrode which makes contact with an end portion of the gate line through a first hole formed through the gate insulation layer, and a second gate pad electrode which makes contact with the first gate pad electrode through a second hole formed through the protection insulation layer. The data pad portion includes a data pad electrode which makes contact with an end portion of the data line through a third hole formed through the protection insulation layer.
