Abstract: A manufacturing method of liquid crystal display device is provided that can increase manufacturing yield by reducing the number of layers and manufacturing costs and by preventing backlight lamp failure. In the manufacturing method of the device, a semiconductor layer 4 and a pixel electrode 5 are formed on a gate insulating film 3. Subsequently, a drain electrode electrically interconnecting the semiconductor layer 4 and the pixel electrode 5 of the pixel region A is formed by overlaying a flat solid conductive film on the substrate, followed by removing the conductive film with the use of a photoresist pattern as a mask, while exposing the semiconductor layer 4 at the pixel region A and the adjacent area C. The semiconductor layer 4 at the pixel region A is etched by using, as an index, an etching amount of the semiconductor layer 4 at the adjacent area.

Abstract: When one signal line group and another signal line group, which differs from the one signal line group in length, are arranged adjacent to each other, a disconnection due to static electricity which is caused by a spark generated between a signal line of the one signal line group and a signal line of the other signal line group can be prevented. For this purpose, the image signal line is specifically configured such that, on a substrate, a first signal line group in which a plurality of first signal lines are arranged in parallel and a second signal line group in which a plurality of second signal lines are arranged in parallel in a region arranged adjacent to the first signal line group are formed, and dummy lines are arranged between the first signal line group and the second signal line group.
