Abstract

This invention presents methods and dispensers which are used for a new way of filling liquid crystal into a LCD cell. The invented methods use the invented liquid crystal dispenser able to release liquid crystal with sufficient controllability at an evacuated atmosphere. Liquid crystal is filled through an inlet of an assembled LCD cell, or filled by laminating an upper substrate with a lower substrate on which liquid crystal has been dropped. The invented liquid crystal dispensers have an opening, in addition to the opening for a capillary, through which interior air bubbles can be released out so as not to be released from the capillary.
