Abstract
An array substrate includes a substrate, a gate line disposed along a first direction on the substrate, and a common line is parallel to the gate line, the common line being of the same material as the gate line. A gate insulating layer is on the gate and common lines, a semiconductor layer is on the gate insulating layer and a transparent pixel electrode includes a drain electrode portion. The drain electrode portion overlaps the semiconductor. A passivation layer includes a first contact hole and an open portion over the pixel and source electrodes, the first contact hole exposing the source electrode and the open portion exposing the pixel electrode, respectively. A data line is disposed along a second direction on the passivation layer, and the data line connected to the source electrode through the first contact hole and crossing the gate line.
