Method for manufacturing liquid crystal display device
First Claim
1. A method for manufacturing a liquid crystal display device, comprising:
- forming a seal pattern comprising a sealant over one of a pair of substrates;
dropping a plurality of droplets of smectic liquid crystal over one of the pair of substrates on which rubbing treatment is performed so that the plurality of droplets are aligned in a direction parallel to a direction of the rubbing treatment; and
attaching the pair of substrates to each other with the sealant to sandwich the smectic liquid crystal,wherein the plurality of droplets spread in the seal pattern.

Abstract
To prevent alignment disorder of liquid crystal molecules, which is caused in manufacturing steps, and to manufacture a liquid crystal display device including a uniform liquid crystal layer in which liquid crystal molecules are aligned with high accuracy. In addition, to provide a technique for manufacturing a liquid crystal display device which is capable of fast response and high performance, and has high image quality with reduced display defects, with high yield. A method for manufacturing a liquid crystal display device, including dropping smectic liquid crystal by a dropping method in which a plurality of droplets of smectic liquid crystal are dropped to an alignment film so that the droplets are aligned in a line which is parallel to a rubbing direction of the alignment film which is formed in a region surrounded by a seal pattern of a sealant over a substrate.
