Abstract
A smectic liquid crystal is injected into a liquid crystal panel according to the vacuum injection scheme. The liquid crystal is applied over an injection port of a blank panel while maintaining the panel at a temperature below a temperature at which the liquid crystal shows a fluidity and controlling the liquid crystal at a viscosity of 0.0005-0.005 kg/ms. As a result, an appropriate amount of the liquid crystal can be applied, thereby providing a liquid crystal panel free from inversion of bubbles and good and uniform alignment free from alignment failure.
