One substrate is supported by an attracting and adsorbing operation and by an adhesive means provided inside a pressurizing plate; the other of substrate, on which a liquid crystal agent is dropped, is supported on a table by an attracting and adsorbing operation or by an adhesive means. Then, the pressure inside the chamber is reduced until a designated reduced pressure level is attained, and the pressure is increased after the substrates come firmly into contact with an adhesive agent that has been provided on the other of substrates, so that the individual substrates are attracted and adsorbed by the pressurizing plate and the table, whereby the substrates are laminated while positioning the substrates. Then, by retracting the adhesive means in the pressurizing plate or the table, the adhesive member is removed from the substrate surface, while or after twisting the adhesive member.

Manufacturing method of liquid crystal display apparatus and substrate assembling apparatus

An apparatus for applying a paste to a surface of a substrate by holding the substrate on a table and by moving a nozzle relative to the table to form a desired paste pattern on the substrate. The apparatus has a device for measuring the position of a paste ejection orifice of the nozzle, a processing unit for calculating, from a result of the measurement by the measuring device, a displacement of the position of the paste ejection orifice when the nozzle is changed, and a mechanism for positioning the substrate at a desired position with respect to the ejection orifice of the changed nozzle on the basis of a result of the operation of the processsing unit. With this arrangement, even if the position of the ejection orifice of the nozzle is changed when the nozzle is changed, the desired positional relationship between the nozzle and the substrate can be set with improved accuracy, whereby a paste pattern can be drawn accurately.
