Abstract
A liquid crystal display includes a substrate, an active layer on the substrate, the active layer having a source region, a channel region and a drain region, a gate line including a gate electrode, the gate electrode overlapping the channel region of the active layer and the gate line having a gate insulating layer disposed underneath, an insulating interlayer covering the exposed surface of the substrate including the gate line, a first contact hole and a second contact hole exposing portions of the source region and the drain region in the insulating interlayer, respectively, a data line including a source electrode on the insulating interlayer, the source electrode connected to the source region and the data line crossing over the gate line, a drain electrode on the insulating interlayer, the drain electrode connected to the drain region, a passivation layer covering the exposed surface of the substrate including the data line and the drain electrode, a third contact hole exposing a portion of the drain electrode on the passivation layer, a pixel electrode connected to the drain electrode on the passivation layer, and a first etching preventing layer covering the crossing portion of the gate lines and the data lines.
