ABSTRACT:
An apparatus for feeding a liquid crystal includes a support member having a rotational axis and capable of rotating about the rotational axis. A thin container is supported by the support member. In that supporting condition, an air discharge port of the container is near to the rotational axis, a liquid crystal feed port is away from the rotational axis, and the air discharge port is open to the atmosphere. The liquid crystal is fed through the feed port while rotating the support member about the rotational axis. Rotation of the support member causes a centrifugal force to be applied to a leading edge of the liquid crystal which has been fed in the container, the direction of the centrifugal force being reverse to a proceeding direction of the leading edge.
