Abstract
A display substrate includes a substrate, a first gate electrode on the substrate, a first gate insulating layer on the first gate electrode, an active layer on the first gate insulating layer, a second gate insulating layer on the active layer, a second gate electrode on the second gate insulating layer, an interlayer insulating layer on the second gate electrode, a first electrode on the interlayer insulating layer to contact a top surface, a side wall, and a bottom surface of the active layer via a first contact hole through the interlayer insulating layer, the second gate insulating layer, the active layer, and a portion of the first gate insulating layer, and a second electrode on the interlayer insulating layer to contact the first gate electrode via a second contact hole through the interlayer insulating layer, the second gate insulating layer, and the first gate insulating layer.
