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.
Claims1
A method of manufacturing a liquid crystal display device, the method comprising:
- forming an orientation film over each of an element substrate and an opposing substrate;
- performing an orientation process to each of the element substrate and the opposing substrate;
- forming a seal pattern from a sealing material on one of the element substrate and the opposing substrate, the seal pattern comprising a first portion and second portions, the second portions of the seal pattern extending up to edges of the one of the element substrate and the opposing substrate so that an injection port is formed at a corner of the one of the element substrate and the opposing substrate;
- joining the element substrate and the opposing substrate;
- separating the joined element substrate and opposing substrate to form at least an empty liquid crystal display device;
- and
- injecting a liquid crystal material into the empty liquid crystal display device through an immersion method, the injecting including employing a V-shape liquid crystal dish in contact with the injection port.
