摘要： It is an object to prevent disordered orientation of liquid crystal molecules which is due to division of substrates even when a liquid crystal dripping method is used, and to provide a method for manufacturing a liquid crystal display device in which liquid crystal is not adversely affected even when a sealant not cured and liquid crystal are in contact. In a method for manufacturing a liquid crystal display device using a liquid crystal dripping method, a scribe groove is provided for at least one of a pair of substrates with a diamond cutter or the like before the pair of substrates are attached under reduced pressure. After the scribing, the pair of substrates are attached under reduced pressure, heat treatment for curing the sealant and aligning the liquid crystal molecules is performed, and the substrates are divided by applying impact using a breaking apparatus.

摘要： A liquid crystal dripping method has a problem in that an uncured sealant increases in width at the time of attaching a pair of substrates and thus a liquid crystal material enters the sealant and unevenness occurs in the inner periphery of the sealant. A region in which reduced is the speed of diffusion of liquid crystal at the time of attaching a pair of substrates is provided between a sealant and an orientation film. Further, time for diffusing the liquid crystal and coming in contact with the sealant is made long. Accordingly, the sealant is subjected to photo-curing before the liquid crystal comes in contact with the sealant. The region in which reduced is the speed of diffusion of the liquid crystal is formed using a material for forming a vertical orientation film, a silane coupling agent, a substance having a photocatalytic function, or the like.

摘要翻译： 液晶滴落方法存在的问题是，在粘附一对基板时未固化的密封剂的宽度增加，因此液晶材料进入密封剂，并且密封剂的内周发生不均匀。 在密封剂和取向膜之间设置有在附着一对基板时液晶的扩散速度降低的区域。 此外，使液晶扩散和与密封剂接触的时间变长。 因此，在液晶与密封剂接触之前，对密封剂进行光固化。 使用用于形成垂直取向膜的材料，硅烷偶联剂，具有光催化功能的物质等，形成液晶的扩散速度降低的区域。
