Abstract

PURPOSE:To inject a liquid crystal into a cell exactly in a short time, by dripping the liquid crystal from a dispenser to a trumpetlike liquid crystal injecting port of a liquid crystal cell placed in an airtight vessel kept in a vacuum state, and after that, pressurizing the inside of the vessel. CONSTITUTION:A liquid crystal display body cell 6 whose substrate is made of a synthetic resin film having a trumpetlike liquid crystal injecting port 6A is placed in an airtight vessel 5, and in the upper direction of this cell 6, a dispenser tip part 12 having a small hole 12A is fixed to a work table 10 which can be rotated up and down and to the right and left. Subsequently, the inside of the vessel 5 is made to a vacuum state by opening a valve 13, the table 10 is moved and is controlled so that a distance between the injecting port 6A and the hole 12A of the tip part 12 becomes constant, and after that, from a liquid crystal vessel 8 which has been cut off from the open air, a liquid crystal 7 of a constant quantity is dripped into the injecting port 6A through a dispenser 9, a feed pipe 11, the tip part 12 and the hole 12A. Subsequently, the inside of the vessel 5 is returned to the atmospheric pressure by opening a valve 14, and the liquid crystal 7 is injected into the cell 6.
