Abstract:
1. A manufacturing method of a liquid crystal display device dropping liquid crystal to at least either one of a first motherboard and a second motherboard, forming a large-sized panel structure that contains a plurality of liquid crystal panel units by pasting together the first motherboard and the second motherboard with sealing material, and cutting the plurality of liquid crystal panel units that contains a plurality of liquid panel units, the method comprising; a preliminary liquid crystal coating process, to coat and discharge liquid crystal to a plurality of cell forming areas of a sample board as well as scan a droplet discharge head toward a predetermined scanning direction under a predetermined discharge condition; a film thickness measurement process, to respectively measure each of the film thicknesses of liquid crystal coated onto the plurality of cell forming areas; a liquid crystal discharge condition calculation process, to calculate a liquid crystal discharge condition to discharge liquid crystal to the plurality of cell forming areas from the droplet discharge head, based on a measuring result of film thicknesses in the film thickness measurement process; and a liquid crystal coating process, to coat liquid crystal to the plurality of cell forming areas in the first motherboard or the second motherboard as well as scan the droplet discharge head toward the predetermined scanning direction in accordance with the liquid crystal discharge condition calculated in the discharge condition calculation process, the liquid crystal discharge condition calculation process further comprising analyzing a fluctuation pattern of the film thickness of liquid crystal measured in the film thickness measurement process on the plurality of the cell forming areas, and calculating the liquid crystal discharge condition of the droplet discharge head discharging to the plurality of cell forming areas in accordance with the analyzed fluctuation pattern.
