Abstract
An array substrate and a method of manufacturing thereof are disclosed for a liquid crystal display device. The array substrate includes a substrate, a gate line disposed along a first direction on the substrate, a common line parallel to the gate line and spaced apart from the gate line, wherein the common line is made of the same material as the gate line. The array substrate also includes a gate insulating layer on the gate and common lines, a semiconductor layer on the gate insulating layer and a pixel electrode of transparent conductive material including a drain electrode portion. The drain electrode portion overlaps the semiconductor layer and a source electrode of transparent conductive material is spaced apart from the drain electrode portion. 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. Alternatively, a method of forming a liquid crystal layer on a substrate having a seal pattern includes preparing a liquid crystal material in a projecting portion, applying a vibration and a pressure to the projecting portion so as to emit the liquid crystal material from the projecting portion, and depositing the emitted liquid crystal material on the substrate.
