1. A method for manufacturing a liquid crystal display device, comprising:
- forming a frame-shaped seal pattern of a sealant, which has an opening at least one corner over a first substrate on which rubbing treatment is performed;
dropping droplets of smectic liquid crystal over the first substrate inside the frame-shaped seal pattern a plurality of times so that the droplets are aligned in a direction parallel to a direction of the rubbing treatment;
attaching the first substrate to a second substrate on which rubbing treatment is performed to make the droplets of the smectic liquid crystal enclosed by the first substrate, the second substrate and the frame-shaped seal pattern; and
spreading the smectic liquid crystal inside the frame-shaped seal pattern.

Abstract
Smectic liquid crystal is dropped 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 having an opening over a substrate. Excess liquid crystal is drained away from the seal pattern of a sealant through the opening of the seal pattern.

-
forming a frame-shaped seal pattern of a sealant, which has an opening at least one corner over a first substrate on which rubbing treatment is performed; dropping droplets of smectic liquid crystal over the first substrate inside the frame-shaped seal pattern a plurality of times so that the droplets are partially overlapped with one another and aligned in a direction parallel to a direction of the rubbing treatment; attaching the first substrate to a second substrate on which rubbing treatment is performed to make the droplets of the smectic liquid crystal enclosed by the first substrate, the second substrate and the frame-shaped seal pattern; and spreading the smectic liquid crystal inside the frame-shaped seal pattern. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
