Abstract
A manufacturing method of a liquid crystal display device enables decreasing the fraction defective of a liquid crystal panel upon manufacturing the liquid crystal display device using the liquid crystal dropping model in a large-sized board. The manufacturing method of a liquid crystal display device includes a preliminary liquid crystal coating process, a film thickness measurement process, a liquid crystal discharge condition calculation process, and a liquid crystal coating process. The preliminary liquid crystal coating process scans a plurality of the cell forming areas of the sample board with a droplet discharge head in a predetermined scanning direction, and coats the liquid crystal with a predetermined discharge condition. The film thickness measurement process respectively measures the film thickness of the liquid crystal coated onto the plurality of the cell forming areas. The liquid crystal discharge condition calculation process calculates the liquid crystal discharge condition to discharge to the plurality of the cell forming areas from the droplet discharge head, based on the measuring result of film thickness. The liquid crystal coating process scans the plurality of the cell forming areas of the first motherboard with the droplet discharge head in the predetermined scanning direction, and coats the liquid crystal in accordance with the liquid crystal discharge condition calculated.
