Abstract
A display substrate includes a base substrate, a common line on the base substrate, a first insulation layer covering the common line and having a first insulating material, a conductive pattern on the first insulation layer and including a source electrode and a drain electrode, a second insulation layer covering the drain electrode and the common line, and including a lower second insulation layer having a second insulating material and an upper second insulation layer having the first insulating material, a first electrode electrically connected to the drain electrode through a first contact hole in the second insulation layer, and a second electrode electrically connected to the common line through a second contact hole in the first and second insulation layers. The upper and lower second insulation layers on the drain electrode have a first hole and a second hole respectively that form the first contact hole.
