PURPOSE: To provide an image forming device manufacturing method having a high yield by preventing the failure to be generated by forming image forming ingredient parts at edge parts of substrates. CONSTITUTION: In an image forming device manufacturing method in which image forming ingredient parts 3 for respectively displaying images are provided on plural substrates 1a to 1d and an image forming device is manufactured by combining respective substrates, auxiliary members 2 being in contact with adjacent surfaces with other substrates at the time of combining respective substrates and whose heights of adjacent surfaces equal to the thickness of the substrates are prepared beforehand every substrate, auxiliary members 2 are arranged by being brought into contact with adjacent surfaces with other substrates every substrate and image forming ingredient parts 3 are formed on respective substrates so that edges of the image forming ingredient part are positioned at borders between the substrate and the auxiliary member 2 and, then, respective substrates are combined after being respectively detached from auxiliary members 2. |
