Abstract
A method of manufacturing a liquid crystal display device by sealing liquid crystals between the substrates relying upon a drop-injection method making it easy to determine a suitable dropping amount of the liquid crystals. The method comprises forming pillar spacers for maintaining a cell thickness on a CF substrate, measuring the height of the pillar spacers, determining the dropping amount of the liquid crystals based on the number of times of executing a step of forming an alignment film again effected for the CF substrate after measuring the height of the pillar spacers, dropping the liquid crystals in the determined dropping amount onto the CF substrate or onto a TFT substrate, sticking the CF substrate and the TFT substrates together in vacuum, and returning the pressure back to the atmospheric pressure to inject the liquid crystals into between the two substrates.
