摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing a liquid crystal display and a substrate superposition device capable of sealing a liquid crystal composition in a short time and minimizing the manufacturing cost. SOLUTION: In the method of manufacturing the liquid crystal display, a sealing compound is applied on a substrate 400M on one side in the form of a loop then the liquid crystal composition is dropped in the loop on which the sealing compound is applied. In addition, the substrate 400M on one side is superposed upon a substrate 600M on the other in the vacuous state then an atmospheric pressure is applied through release into the atmosphere and a gap between a pair of the substrates is pressurized until a predetermined interval is provided then the sealing compound is cured and bonded. In the substrate superposition process, the principal plane of the substrate 600M on the other is bonded and kept by means of a retaining pad 702 provided with a tacky holding agent 704 then the substrate 400M on one side is superposed thereupon.

摘要： PROBLEM TO BE SOLVED: To make a sealing width uniform, without the generation of spacer column foam in a seal at single-substrate sealing of liquid crystal cells with sealing material by providing the device with columnar spacers, exclusive of regions where the sealing material spreads at sealing stage. SOLUTION: A sealing material 24 is applied at the region which is the pixel region circumference of a first substrate, formed with the columnar spacers 26 and sealing part columnar spacers 27 and is apart by 500 μm from the columnar spacers 26 exclusive of an injection port, in such a manner that a width of 300 μm is set. As a result, the single-substrate sealing for heating the sealing material 24 by one sheet each is executed, in order to improve the gap accuracy of the liquid crystal cell 20a, with which the spacing is uniformly held by the columnar spacers 26 and to shorten the sealing stage time. Even if the width thereof is rapidly increases, the columnar spacers 26 are not arranged in a region where the sealing material 24 spreads, and therefore, the remaining spacer column foam in the sealing material 24 does not occur in spite of the rapid spreading of the sealing material 24 and the stable sealing width can be obtained. Then, a good satisfactory sealing free from peeling is obtained.

摘要： PROBLEM TO BE SOLVED: To provide a coating device for a printing material which can manufacture a liquid crystal display device of high quality by improving printing defects. SOLUTION: A gas density measuring instrument 20 measures the density of solvent gas inside a partition sealing a coating unit for applying a printing material. When the measured value is less than the saturated vapor pressure of a solvent, a main control part 41 drives a gas supply device 30 to supply the solvent gas into the partition and when the measured value is higher than the saturated vapor pressure of the solvent, the main control part 41 drives a discharging device 15 and an air suction device 16 to discharge the atmosphere containing the solvent gas in the partition and suck the outside air. Thus, the solvent gas density in the partition is adjusted to density corresponding to the saturated vapor pressure of the solvent to suppress the volatilization of the solvent from the printing material of the coating unit.

摘要： PROBLEM TO BE SOLVED: To manufacture a liquid crystal display panel provided with excellent display characteristics. SOLUTION: At the time of applying a sealing member 20 to a first substrate 10, the sealing member 20 is extended so as to make the tips TP of seal pull-out parts 20b in the sealing member 20 reach a chamfering part 10a. The first substrate 10 and a second substrate 12 are assembled, liquid crystal is injected from an injection port 22 and then, the injection port 22 is sealed by the sealing member 24. Since the tips TP of the seal pull-out parts 20b in the sealing member 20 are positioned at the chamfering parts 10a and 12a of the first and second substrates 10 and 12, the sealing member 20 and the sealing member 24 are more surely brought into contact. Thus, foreign matters are prevented from entering the liquid crystal and this liquid crystal display panel provided with the excellent display characteristics is manufactured.
