ABSTRACT:
The present invention provides a simple method of combining two plate members, using an equalizing mechanism holding one of the two plate members so that the plate member is properly preloaded and can be turned by the least necessary force, and capable of combining the two plate members so that the respective contact surfaces of the plate members are joined closely and accurately, and a plate member combining device for carrying out the method. An XY-table 701 supporting a lower holding unit 5 having a holding plate 513 capable of being turned on support pins 505 and 511 about two axis perpendicular to each other and holding a TFT plate 11 is lifted up by a lifting table 703 to bring the TFT plate 11 into partial contact with a color filter plate 9 held by an upper holding unit 3 disposed above the lower holding unit 5, and then the XY-table is lifted up further to bring the respective contact surfaces 901 and 1101 of the color filter plate 9 and the TFT plate 11 into close contact with each other while the XY-table 701 is moved along a minute square path in a horizontal plane in order that the holding plate 513 can be easily turned on the support pins 505 and 511 in a minute range.
