ABSTRACT:
Relating to a method of manufacturing a liquid crystal display device, minimizing liquid crystal material loss and use of cleaning solvent, and providing a liquid crystal display device in which a seal pattern having few gap inconsistencies are taken as a objective. Liquid crystal material wraparound can be prevented by forming a seal stopper portion outside a peripheral seal portion, and in addition, by increasing the degree of symmetry of the seal pattern and by forming a damming portion between injection ports, gap inconsistencies within the liquid crystal display device can be reduced.
