Abstract
A liquid crystal sealing device which supplies sealing material for sealing liquid crystal injection holes of sealing areas of a multiplicity of liquid crystal cells simultaneously. This device has a multiplicity of pins which are arranged to match the arrangement of the sealing areas of the multiplicity of liquid crystal cells so that the sealing material can be transferred from a container storing the sealing material to the corresponding sealing area of the liquid crystal cell. This device also has a reciprocating mechanism for reciprocating the multiplicity of pins, as one unit, between a position where the sealing area is to be positioned and the container. This device also has a vertical micro-motion mechanism which minutely moves each one of the multiplicity of pins vertically, with the position, which is designed to be the position for attaching the sealing material to the sealing area, as the center, and a horizontal micro-motion mechanism which minutely moves each one of the pins horizontally, with this designed position as the center.
