Abstract:
The present invention disposes a plurality of measuring marks on a dummy region having a seal line to detect a position and a width of the seal line during a fabrication process of a liquid crystal display device and then process can be terminated without further processes in case of bad quality of the seal line, thereby process delay and cost may be minimized.
