Abstract: PROBLEM TO BE SOLVED: To provide an array substrate for liquid crystal display device and a fabricating method of the same, capable of improving the process yield by reducing a manufacturing cost and time through further simplification of mask processes. SOLUTION: The array substrate for liquid crystal display device is manufactured by using a mask having half transmitting portions of slit widths different from each other upon the second process. Thereby, on the ashing process of a photosensitive layer, etching ratio on a part where wiring is positioned is equalized to the etching ratio on a part where the wiring is not positioned and, therefore, the advantage of preventing a defect from occurring on the surface of the wiring can be obtained. This invention is also characterized in that the array substrate is manufactured through three mask processes. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To prevent influences of drop and time delay of a common voltage without using a third drive circuit which functions as a common drive circuit in a prior art, and to calculate and compensate distortion resulting from the time delay of the common voltage signal. SOLUTION: This liquid crystal display includes scan lines 124, data lines 123, thin film transistors 121, pixel electrodes 150, a single common line 100 disposed outside a display area in parallel with the scan lines 124, and a first connecting terminal 130 disposed on the single common line 100. The common line 100 is connected to a common electrode 114 through silver dots 130, 131. A wave form of the common voltage applied on a second common pad 210 can be calculated because the second common pad 210b is not connected to a first common pad 210a, thereby giving no obstacle to detection of input common voltage and output common voltage. Therefore, distortion of the common voltage wave form or the amount of the drop down voltage of the common voltage occurring in the central portion of the display area can be exactly calculated.
