  • Method and apparatus for manufacturing an LCD
    Patent number: 7701546
    Abstract: A method of manufacturing an LCD comprising, preparing a liquid crystal panel which comprises a substrate assembly and a polarizing plate, wherein the polarizing plate is attached to the substrate assembly, disposing a gas injecting part towards the plate surface of the liquid crystal panel, while the gas injecting part is exposed to atmospheric conditions, and applying a pressure to the plate surface of the liquid crystal panel by injecting gas through the gas injecting part. With this configuration, the present invention provides a method to remove bubbles between the polarizing plate and liquid crystal panel without the use of a chamber.
