Patent ID: 7714949

Claim:
A thin film transistor (TFT) array substrate for a liquid crystal display (LCD) device assembled with the array substrate and a color filter substrate having a liquid crystal layer interposed therebetween, comprising: a substrate; at least one gate line and at least one data line formed on the substrate and defining at least one pixel area; a pixel electrode formed in the pixel area; a light blocking bar located at the periphery of the pixel electrode; a thin film transistor formed in the pixel area and comprising a gate electrode as a part of the gate line, a source electrode connected with the data line, and a drain electrode connected with the pixel electrode; and at least one common electrode formed on the substrate overlapped with the pixel electrode to form a storage capacitor with the pixel electrode, and wherein a part of the drain electrode at which the drain electrode is connected with the pixel electrode is overlapped with the common electrode; wherein the gate line, the common electrode, and the light blocking bar are formed of the same material in the same process.
