Abstract:
1. A display substrate, comprising: a gate line formed on a base substrate and extending in a first direction; a data line formed on the base substrate and extending in a second direction crossing the first direction; a switching element formed in a unit pixel and electrically connected to the gate line and the data line; a storage line formed on the base substrate; an organic insulation layer formed on the base substrate, the organic insulation layer having a hole formed within the area of the unit pixel and extending from a contact area formed at a portion of the drain electrode of the unit pixel to a portion corresponding to the storage line thereof; and, a pixel electrode corresponding to the unit pixel formed on the organic insulation layer and overlapping with the storage line and making electrical contact with the contact area of the unit pixel through the hole, wherein a storage capacitor is defined by the storage line and the pixel electrode, and the storage line overlaps an edge portion of the contact area of the unit pixel.
